Fill September Daycare Openings: May–August Playbook

If you’re reading this in May, you’re sitting at the front edge of the most important enrollment window of your year.

Childcare runs on an academic calendar whether you want it to or not. Kindergarteners exit in late August. Toddlers age into preschool rooms in September. Babies whose parents wrapped maternity leave at twelve weeks need care by fall. Every one of those movements creates an opening, and every one of those openings is a family decision being made right now — not in August.

And yet the most common pattern we see across centers is exactly the opposite. Directors notice the September openings in late July, panic in August, and scramble to fill them through Labor Day. By the time the offers go out, half the parents who would have said yes in June have already enrolled somewhere else.

This guide flips that timeline. It’s a month-by-month playbook for May, June, July, and August — with the specific actions, the email scripts, and the forecasting math — so you fill September openings before the seats are even empty.

Why Parents Pick September Daycare Spots in May (Not August)

Three things drive the May–July decision window, and understanding them is the difference between proactive planning and August panic.

1. The kindergarten cascade starts in spring

Public school kindergarten registration in most districts happens in March, April, and May. The moment a parent confirms their five-year-old is starting kindergarten in August or September, they know that child’s younger sibling needs a daycare spot too — and they start looking immediately. Every single kindergarten registration in your community triggers a chain of childcare decisions, and most of those decisions get made within 30 days.

2. Maternity leave timing locks in by mid-spring

The average US maternity leave is 12 weeks. A baby born in May or June will need infant care by August or September. Parents in those situations are not waiting until they return to work to start looking — they’re looking the moment they finalize their leave dates, which is typically 8–12 weeks before delivery. That means May and June are the peak months when these families call you.

3. Move-up cascades happen on a fixed calendar

Every child who ages into the next room frees up a seat behind them. If your toddler room has four kids turning three in July and August, that’s four preschool seats opening (which creates four toddler openings, which creates four infant openings). These transitions happen on the calendar; they’re not random. Forecasting them is a fifteen-minute exercise. We covered the full mechanics in our guide to daycare enrollment forecasting, but the short version is: every birthday in your roster is a clue about when a seat will open.

How Many September Openings Will You Actually Have?

Most directors underestimate this number, which is a big part of why they wait too long to act. The pattern across centers we work with is remarkably consistent. For a typical 100-child licensed program with the standard age-group mix:

• 3–5 kindergarten exits in late August (kids leaving the pre-K room for elementary school)
• 2–3 family relocations over the summer (jobs, moves, schedule changes)
• 4–6 age-group transitions triggered by birthdays in July–September
• 1–2 unplanned departures (custody changes, financial changes, schedule mismatches)

Add it up: roughly 8–12 fresh openings between mid-August and late September. At a typical $1,200–$1,800/month tuition per seat, that’s $9,600–$21,600 in monthly recurring revenue waiting to be captured — or lost.

The fill speed difference between a planned and reactive approach is huge. Centers that have a list of contacted, interested families in May fill those September openings in 2–7 days each. Centers that wait until August advertise the openings cold and average 3–4 weeks per fill. On 8 openings, that’s 24–32 cumulative empty-seat-weeks at roughly $300/week each — a $7,000–$10,000 swing in revenue between the two approaches, every fall.

If you want to plug your own numbers in, our empty-seat cost calculator will give you a real dollar figure for what slow fall fills are costing your specific center.

Your May–August Playbook (One Hour a Week)

The whole campaign fits into about an hour a week. Here’s what to do, in order.

May: Audit, forecast, and warm the list

• Clean your waitlist. Every family who hasn’t confirmed interest in 90+ days gets a still-interested email this week. Anyone who doesn’t respond gets archived. Do not run a fall campaign against a list full of families who already enrolled elsewhere — it skews your numbers and wastes your time.
• Forecast September openings by classroom. List every child whose birthday falls between July 1 and September 30. Note which room each one ages out of and into. Cross-reference with your kindergarten exits. By the end of this exercise you should have a number per room (“infant: 2 openings, toddler: 3, preschool: 2, pre-K: 0 net”).
• Send the May preview email (template below). Goes to every active family on your waitlist, segmented by age group. The email doesn’t make offers — it warms the list and asks who’s still in, so you know who to prioritize when you start scheduling tours in June.
• Tag your priority families. Siblings of currently enrolled, employees, second-time inquirers, alumni — these get offered first. If your priority tiers exist only in your head, write them down now.

June: Tour the priority list

• Schedule tours with everyone who responded to the May preview. Aim for 2–3 tour slots per week. Tours that happen in June convert at roughly 2× the rate of tours that happen in late August, because parents have time to reflect and aren’t rushing to a decision.
• Send first offers to families whose desired start date matches an opening you’ve forecasted. Be specific in the offer: classroom, exact start date, deadline to accept (48–72 hours typical). Vague offers (“we think we might have something”) get ignored.
• Track tour-to-offer-to-acceptance rates for each family. By the end of June you want a clear list of who’s likely to enroll, who’s 50/50, and who’s drifted away.

July: Second-wave offers and follow-up

• Send the July update email to anyone who hasn’t responded yet. This is your second touch for parents who saw the May email but didn’t act — some of them are now ready to commit, especially the maternity-leave parents who finalized their dates in June.
• Move June tour-takers to a decision. Anyone who toured but didn’t accept an offer needs a direct ask: ‘We’re holding the August 18 spot for you until Friday — are you in?’ Avoid open-ended waiting. Parents respect a deadline.
• Confirm September starts in writing. Every accepted offer should have a signed enrollment agreement and deposit by July 31. Anything still verbal at that point is at risk.

August: Final fills and onboarding

• Last-call email to your remaining waitlist. Be direct: ‘We have 2 spots opening September 8. If you’re still interested, reply by Friday.’ You’ll get more responses than you expect — some families have been waiting for a deadline.
• Onboard September starters. Send welcome packets, schedule first-day meetings, share parent portal access. The families you closed in May and June need to feel taken care of so they don’t back out at the last minute.
• Refresh the waitlist for the next cycle. Spots that didn’t fill in September will likely fill in October or November — and the families who toured but didn’t enroll for September often become the first calls when those later spots open.

Three Drop-In Email Scripts (Send These This Month)

These three messages cover the May–August arc. Copy them, swap in your center’s name, and send. If you want a fuller library of waitlist emails, our 6-template post covers every other stage.

1. The May preview email

Subject: Quick September openings preview from [Center Name] Hi [Family Name], we’re mapping out September openings for the [age group] room and wanted to give the families on our waitlist the first heads-up. Right now we’re forecasting [2–3] spots opening between mid-August and late September. If [child’s name] is still looking for care to start this fall, reply with a yes (or a maybe) and we’ll get a tour on the calendar in the next few weeks before things fill up. If you’ve found care elsewhere, reply with a quick note so we can take you off the list — no hard feelings, we just want to keep the list real.

2. The June offer email

Subject: A September spot for [child’s name] — holding it through Friday Hi [Family Name], we’re ready to offer [child’s name] a spot in our [age group] room starting [exact date]. Tuition is [amount]/month and the enrollment packet is attached. We can hold this spot through [Friday at 5pm]. To accept, reply yes and we’ll send the agreement to sign. If you need more time, reply with a question — we’d rather work it out than have you go silent. Looking forward to having you with us.

3. The August last-call email

Subject: Last call — September spots at [Center Name] Hi [Family Name], wanted to circle back one more time. We have [number] September openings still available in the [age group] room, starting [date]. After this round we won’t be able to hold spots open — they’ll go to families on the wider waitlist. If you’re still interested, reply by [Friday] and we’ll send an offer the same day. If now isn’t the right time, no problem — we’ll keep your info on file for spring openings.

How to Forecast September Openings (Even Without Software)

You don’t need a tool to do this — you need 30 minutes and a spreadsheet. Here’s the manual approach.

1. List every currently enrolled child with their date of birth and current classroom.
2. Mark every child whose birthday falls between July 1 and September 30. These are your transition candidates — they’ll likely move to the next room before Labor Day.
3. For each transition candidate, note which room they’re leaving and which room they’re joining. Most rooms have age cutoffs (e.g., ‘toddler room serves 12–24 months’). A child turning 24 months in August is leaving the toddler room.
4. Add your kindergarten exits. Anyone in your pre-K room aged 5+ by September 1 is gone. Most districts have firm cutoff dates; check yours.
5. Subtract anyone you already know is leaving for other reasons (move, schedule change, parent decision).
6. Net the result by classroom. That’s your September forecast. Do this exercise in May; revise in late June.

If you’d rather not maintain this manually every quarter, software like Seedlist runs the same calculation automatically from each child’s DOB and your room age cutoffs — the forecast updates in real time as new families join the waitlist. Either way, having the forecast in front of you in May is what unlocks everything else in this playbook.

The 4 Most Common Fall Enrollment Mistakes

Across the centers we’ve seen run good and bad fall campaigns, the failure modes are remarkably consistent. Avoid these four and you’ll outperform most of your local competition.

1. Waiting until August to start

By August, the families who would have committed in May are already enrolled at a center down the road. The directors who say ‘I always fill in August’ usually mean ‘I fill 60% of my openings in August and the rest sit empty until October.’ The early months aren’t optional — they’re where the highest-intent families are decided.

2. Only contacting the ‘yes’ families

Roughly 30–40% of families who said ‘maybe’ in March will say ‘yes’ by July if you check back. Directors who only follow up with hot leads leave the maybe pile untouched and lose the conversions that were one nudge away.

3. Generic openings emails

‘We have openings in the fall’ sent to your full list converts at roughly 2–4%. The same email segmented by age group and personalized with the child’s name and a specific date converts at 15–20%. Take the extra ten minutes per email — the math is overwhelming.

4. Forgetting the cascade

When a child ages into the next room, they free a seat behind them. Many directors fill the obvious openings (kindergarten exits) and miss the cascade openings further down (the infant seat that opens because the toddler moved up because the preschooler moved up because the pre-K kid started kindergarten). Our classroom transitions guide walks through how the cascade actually works.

What If You Don’t Have a Waitlist Yet?

If you’re reading this and realizing your ‘waitlist’ is a stack of post-its or a spreadsheet you haven’t opened in months, the honest answer is: you can still salvage September, but you have about two weeks to act.

Build the waitlist first — even a basic Google Sheet with name, child DOB, parent contact, desired start date, and ‘how did you hear about us’ is enough to start. Push the sign-up link out through every channel you have (your website, your Facebook, the QR code on your front door, the email signature your assistant director uses). Our build-from-scratch guide walks through the specifics for centers starting from zero.

If you have an old spreadsheet that’s gone stale, our migration guide covers how to clean it up and get it usable in a single afternoon. Either path is better than spending May without a list to work from.

After September: The Work That Sets Up January

September fill is a milestone, not the finish line. The families you toured but didn’t place this fall are exactly who you’ll call first when January spots open from holiday schedule changes and second-semester moves. Keep them on the list. Send a quick ‘thanks for considering us, here’s where you stand for spring’ message in October so they remember you exist.

And then start the January planning the same way you started May: forecast openings, warm the list, run the playbook on a tighter timeline. The centers that consistently run at 90%+ occupancy are not the ones with magic marketing — they’re the ones who treat enrollment as a quarterly cycle instead of an annual scramble.

Frequently Asked Questions

The Bottom Line

Fall enrollment isn’t magic and it isn’t luck. It’s a calendar exercise that rewards directors who start early and follow through. The families who will fill your September seats are deciding right now — the only question is whether they’re hearing from you in May or finding out about your openings the same week your competitor down the road sends them an offer.

Block one hour this week. Run the May actions. Send the preview email. By the end of the month you’ll have a forecasted list of openings and a warm list of families to fill them with — and the rest of summer becomes the easiest enrollment cycle of your year.
