Nesting Checklist by Week: A Room-by-Room Third Trimester Guide
Start nesting around week 28 and aim to have the essentials done by week 36, since many babies arrive before their due date. Work room by room: a safe sleep space and anchored furniture by week 32, first clothes washed and sorted by week 34, and the car seat installed and hospital bag packed by week 36. Save weeks 37–40 for rest.
If you're in the third trimester, you may have gift bags stacked in the spare room, a car with no car seat, and a sudden urge to reorganize the pantry at 11 p.m. This nesting checklist by week turns that urge into a plan. Each room gets its own list, and every task has a target week, so you can see what matters now and what can wait.
How to use this third trimester checklist
Each task below has a target week and a countdown, so "30 (10 to go)" means week 30, ten weeks before a 40-week due date. The big jobs come first, so the essentials are done by week 36 with a buffer if baby is early.
- Starting late? Do the lowest week numbers in each room first, and focus on the five essentials below. The rest can wait or go to a helper.
- Carrying twins or expecting an early delivery? Ask your provider which week to aim for, and shift the whole plan earlier.
- Second baby? Much of this list becomes a check of what you already own. Our guide to preparing for your second baby covers what's worth re-buying.
- Want a printable nesting checklist? Print this page or save it as a PDF, then post each room's table where that work happens: the nursery list inside the closet door, the kitchen list on the fridge.
If you only get to five things, make them these: a safe place for baby to sleep, the car seat installed, the hospital bag packed, a week of newborn clothes washed, and diapers and wipes stocked.
Nursery (or wherever baby sleeps first)
| Do by week | Task | Why then |
|---|---|---|
| 29 (11 to go) | Decide where baby will sleep for the first few months. | It tells you what to build first. |
| 30 (10 to go) | Assemble the crib or bassinet with a firm, snug-fitting mattress. Skip old drop-side cribs. | Missing hardware or the wrong mattress size takes time to replace. |
| 31 (9 to go) | Set the layout: place the crib or bassinet away from windows, blind cords, and anything hung on the wall. | Layout is hard to change once furniture is anchored. |
| 32 (8 to go) | Anchor dressers, bookcases, and the changing table to the wall. | Do it once the layout is final. |
| 33 (7 to go) | Set up a changing station: newborn and size 1 diapers, wipes, diaper cream, two pad covers, a lidded bin. | You'll use it within hours of coming home. |
| 35 (5 to go) | Add a dim lamp, a comfortable chair, and a spot to set down a water bottle. | Sit there once after dark and you'll spot what's missing. |
| 36 (4 to go) | Final check: fitted sheet only, nothing in or over the sleep space. | Shower quilts and plush toys tend to land in the crib by default. |
The American Academy of Pediatrics recommends room-sharing, not bed-sharing, ideally for at least the first six months, so your "nursery" may start as a bassinet beside your bed. The CPSC's safe sleep page covers crib and bassinet basics. The rule to hold onto: a firm, flat surface with only a fitted sheet, and nothing hanging over the crib or bassinet.
Closet and dresser
| Do by week | Task | Why then |
|---|---|---|
| 30 (10 to go) | Gather every gift and hand-me-down in one spot. Set aside anything with loose buttons, broken snaps, or drawstrings. | You can't sort clothes spread across three rooms. |
| 31 (9 to go) | Sort by size: newborn, 0–3, 3–6, 6–9, 9–12, and 12 months up. Bin and label everything 6 months and up. | Gaps show up in time to fill them. |
| 32 (8 to go) | Leave tags on bigger sizes and extra newborn pieces. Keep gift receipts in one envelope. | Some babies skip newborn size, and return windows close. |
| 33 (7 to go) | Wash about a week of newborn clothes, all of 0–3, and the crib sheets, swaddles, and burp cloths. | Laundry is easier now than at week 39. |
| 34 (6 to go) | Hang or fold by size, smallest in front, with a divider between each size. | Anyone helping can find the right size without asking. |
| 35 (5 to go) | Fill one "grab" drawer with sleepers, bodysuits, socks, and swaddles. Add an empty bin for outgrown clothes. | The first weeks run on a handful of pieces. |
For quantities, our guide to how many clothes a newborn actually needs breaks it down by size, which makes the week 32 return pile easy to decide.
Week 34 is the step that keeps the closet working after baby arrives. Labeled tabs between sizes mean a partner or grandparent can grab 0–3 without digging through 3–6. Index cards and binder clips do the job. If you'd like something sturdier, our Newborn Closet Divider Set ($28) is 1/8-inch etched birch wood and covers newborn through 24 months, so the system keeps going after the newborn clothes are packed away.
Kitchen
| Do by week | Task | Why then |
|---|---|---|
| 30 (10 to go) | Clear out the freezer and toss anything old. | Freezer meals need room. |
| 31 (9 to go) | Cook double batches two or three nights a week through week 36 and freeze half. Soups, chili, burritos, and baked pasta freeze well. Label each with the name, date, and reheating steps. | A stash builds without a whole weekend of cooking. |
| 32 (8 to go) | Clean the fridge and oven with the windows open, skipping cleaners with strong fumes. | Your last easy chance for a while. |
| 34 (6 to go) | Stock one-handed snacks: granola bars, crackers, nut butter, instant oats, cheese sticks. | Sit-down meals get rare in the newborn weeks. |
| 35 (5 to go) | Set up a feeding spot. For bottles, wash and sanitize them per the maker's instructions and clear space for a drying rack. For nursing, fill a basket with a water bottle, snacks, burp cloths, and a charger. | You'll use it the first day home. |
| 36 (4 to go) | Save a grocery delivery order and list easy jobs for helpers, like dropping off dinner or walking the dog. | When someone asks "what can I do?" you'll have an answer ready. |
Car
| Do by week | Task | Why then |
|---|---|---|
| 30 (10 to go) | Buy or confirm your car seat. On a hand-me-down, check the expiration date on the label, and skip it if you don't know its crash history. | You need it for the ride home. |
| 33 (7 to go) | Install it rear-facing in the back seat, following both the car seat manual and your vehicle's manual. | Installs are fiddly; leave time for a second try. |
| 34 (6 to go) | Have the install checked by a certified child passenger safety technician. | Appointments can book up. |
| 35 (5 to go) | Practice on a stuffed animal: chest clip at armpit level, straps snug enough that you can't pinch extra webbing at the shoulder. | Learn the buckle before baby's first ride, not during it. |
| 35 (5 to go) | Pack a car kit: diapers, wipes, a spare outfit, a burp cloth, a few bags. | Blowouts don't wait until you're home. |
| 36 (4 to go) | Fill the tank, find the hospital's after-hours entrance and parking, and keep bags by the door. | No hunting for a door mid-contraction. |
NHTSA's car seat page covers seat types and how to find installation help near you. Due in winter? Bulky coats don't belong under car seat straps, and our winter baby preparation guide covers what to use instead.
Your bedroom and bathroom
| Do by week | Task | Why then |
|---|---|---|
| 33 (7 to go) | Stock a bathroom basket with the postpartum supplies your provider suggests. With stairs, set one up on each floor. | Easy to forget until the moment you need them. |
| 34 (6 to go) | Set up a bedside station: water bottle, snacks, charger, lamp, burp cloths. | Night feeds go easier with everything in reach. |
| 34 (6 to go) | Put a second diaper caddy in the main living area. | Saves a trip to the nursery for every change. |
| 35 (5 to go) | Pack hospital bags for you, baby, and your partner or support person. | Ready well before the due date, with room to spare. |
| 35 (5 to go) | Put a waterproof protector and fresh sheets on your bed. | Cheap insurance for the weeks before and after birth. |
Support people need a bag too. Our hospital bag checklist for partners and support people covers what goes in theirs.

What to hand off while nesting
The urge to nest is real, and some of these jobs are heavier than they look. Hand off anything that involves:
- Ladders or step stools, like hanging curtains or reaching high shelves
- Lifting or moving furniture, including anchoring it
- Paint, varnish, or cleaners with strong fumes (if the nursery needs paint, have someone else do it early and air the room out well)
- Long stretches on your feet; split big jobs into 30-minute chunks
If you're unsure whether a task is a good idea, ask your OB or midwife.
You don't need a finished, photo-ready nursery by week 36. You need a safe place for baby to sleep, a car seat that's installed right, a bag by the door, and clothes you can find in the dark. Pick this week's row for each room, do those, and let the rest wait.
Frequently asked questions
When should you start nesting during pregnancy?
The urge to nest often shows up in the third trimester, and week 28 is a practical time to start the bigger jobs. Aim to finish the essentials by about week 36 so you have a buffer if baby arrives early. If you have energy sooner, sorting clothes and clearing the freezer can start in the second trimester.
What if you're starting your nesting checklist at 37 weeks?
Go straight to the essentials and hand off the rest. A safe place for baby to sleep, an installed car seat, and a packed hospital bag come first, then a few washed outfits and a pack of diapers and wipes. Freezer meals and closet systems can wait until after the birth or go to a helper.
Should you wash all baby clothes before the baby is born?
Wash the first size or two, plus crib sheets, swaddles, and burp cloths. Leave tags on larger sizes and extra newborn pieces until you know what fits, since some babies skip newborn size and unwashed clothes are easier to return. If your baby has sensitive skin, ask your pediatrician about detergent.
When should you install the car seat before the baby comes?
Around 33 to 34 weeks works well. That leaves time to have a certified child passenger safety technician check the installation before week 36, and to practice adjusting the harness. Follow both the car seat manual and your vehicle manual when you install it.
Is there a printable nesting checklist?
You can print this page from your browser or save it as a PDF. Post each room's table where that work happens, like the nursery list inside the closet door and the kitchen list on the fridge. The week-by-week list works well as a single page to check off as you go.
