Third Trimester Checklist: What to Do Before Baby Comes

What should you do in the third trimester before the baby comes? Make decisions, not purchases. That’s the club’s collective answer after a few dozen first years: the moms who felt most ready weren’t the ones with the fullest nurseries — they were the ones who had already decided who’s on the night shift, who’s allowed through the front door, which pediatrician gets the 2am call, and what happens at work while they’re gone. This checklist is all of that, in the order the club would tackle it. Nothing on it can be shipped in a box.

Weeks 28–32: the decisions that need two people

Write the night-shift split. Who takes which hours, who covers weekend mornings, what “off duty” actually means. Every couple in the club that skipped this had the same fight in week two; every couple that did it reports the fight simply never happened.
Set the visitor policy. When visits start, how long they run, who gets the early slots. Decide it now, while you’re both rested and nobody is ringing the doorbell — the full plan lives in our fourth trimester checklist.
Agree where the baby sleeps. Pick a safe, repeatable setup with your pediatrician’s blessing so nobody is redesigning the arrangement at 2am on night three.
Have the money conversation. Not a budget spreadsheet — just the honest version of “what does leave do to our income, and what are we pausing for six months?” One club mom calls this “the talk that made every later talk easier.”

Weeks 30–34: the people setup

Choose the pediatrician. Many practices do a meet-and-greet visit; take it. You’re choosing the person you’ll call at midnight, so pick for reachability as much as reputation.
Name your inner circle. The two or three people who can see your house at its worst and hold the baby while you shower. Deciding who they are now removes a hundred tiny negotiations later.
Start your help list. A running note of concrete jobs — dishwasher, dog walk, holding the baby from 2 to 4 — so “let me know if you need anything” lands on a task. The club’s full system is in the help list.
Find one mom a few steps ahead. A birth-class group chat, a neighbor, a cousin. The club exists because this single item carried us further than anything with a barcode.

Weeks 32–36: work and paperwork

Run the leave logistics. Confirm dates in writing, build the handover doc, set your boundaries for while you’re out. The complete work-side version is our maternity leave checklist — do it in this window, not in week 39.
Preview the paperwork. Birth certificate, Social Security card, adding the baby to your insurance — most of it starts at the hospital, but the follow-ups have deadlines. Skim the newborn paperwork checklist now so nothing lands on you cold.
Do the boring errands early. Refill your prescriptions, sort anything with a deadline in the next three months, and get the car seat professionally checked — many fire stations and hospitals do it free.

Weeks 36–40: the final sweep

Cook nothing; arrange everything. Say yes to the meal train if anyone offers to run one. If nobody offers, ask the friend who loves a spreadsheet — the club swears it’s a gift to her too.
Write the announcement draft. One saved message that says the baby arrived and when you’ll be up for visits. Composing it now beats composing it fourteen times from a hospital bed.
Pre-book your own appointments. Your postpartum checkup, a dental cleaning, anything for you that’s easier to schedule now than to remember later.
Lower the bar, out loud. Agree with your partner what “clean enough” and “fed enough” mean for the first three months. Resentment loves an unspoken standard.
Plan one thing that stays yours. A weekly walk, a standing call, a show you don’t share. Club consensus: the moms who kept one non-baby thread felt like themselves sooner.

Heard in the club: “I spent the third trimester washing tiny socks. I should have spent one afternoon of it deciding things with my husband. The socks did not help at 3am.”

FAQ: the third trimester to-do list

When should I start my third trimester checklist?

Around week 28 is the club’s sweet spot — early enough that nothing is urgent, late enough that the decisions feel real. Most of this list is conversations and calendar entries; an afternoon a week covers it comfortably.

What should I do in the third trimester besides buying things?

Decide the night-shift split, the visitor policy, and where the baby sleeps; choose your pediatrician and your inner circle; sort your leave and preview the paperwork deadlines. Moms in the club consistently rank these above anything that arrived in a box.

What do first-time moms forget in the third trimester?

By the club’s collective confession: their own appointments, the leave handover, and the help list. The baby’s needs are well-marketed; yours aren’t. Anything on this list that’s about you, the person, is the part most likely to get skipped — and most missed later.

How is this different from a hospital bag or registry checklist?

It’s the part registries can’t cover. Bags and gear lists live elsewhere; this is the people, plans and paperwork that decide how the first weeks actually feel. If an item can be purchased, it doesn’t belong on this particular list.
