The nursery does not need to be finished the day you find out you are pregnant. It also cannot still be a home office at 38 weeks with paint cans unopened on the floor.
Somewhere between those two extremes is the right timeline. And for most families, that timeline runs through the second trimester with final touches in the third. Here is exactly when to do what, so nothing is left to the last chaotic weeks before your due date.
First Trimester: Think, Don’t Buy
Weeks one through twelve are for ideas, not purchases. Energy is low, nausea is real, and the pregnancy is still early enough that many families are not ready to commit to a fully assembled nursery. That is completely fine.
What is worth doing in the first trimester is the thinking work that sets everything else up.
Decide on the room. If you have a dedicated space for the nursery, walk through it with fresh eyes. What is currently in there that needs to move? Are there repairs needed, floors that need replacing, or walls that need patching? Structural work takes time and disruption. Identifying it now means it can be scheduled without pressure.
Set a budget. Nursery costs vary enormously depending on how elaborate you go. A functional nursery with quality essentials can be done thoughtfully. A designer nursery costs significantly more. Know which you are building before you start buying things.
Start collecting inspiration. Scroll, save, pin. Build a picture of the colour palette, the style, and the overall feel you want. This is genuinely the fun part and the first trimester is a good time for it because it costs nothing and requires no energy beyond looking.
Measure the room. Sketch a rough floor plan. Mark where the doors and windows are. Note any radiators, vents, or electrical points. This becomes essential when ordering furniture, because a crib that looks perfectly sized online can be awkward in your specific room with your specific door swing.
Second Trimester: This Is When You Do It
Weeks thirteen through twenty-seven are the window. Energy is typically better than the first trimester and significantly better than the third. You can still move comfortably and get things done without everything being an enormous physical effort.
This is when the actual nursery takes shape.
Weeks 14 to 18: Finalise the Plan
Lock in your colour palette and theme. Choose your paint or wallpaper. If you are hiring anyone to help with decorating or if major work is needed in the room, book them now. Good tradespeople book weeks out and this is not the time to discover a four-week wait when you are 35 weeks pregnant.
Order your main furniture at this point as well. Furniture delivery timelines vary and some pieces take four to eight weeks to arrive, sometimes longer. Ordering now means everything arrives in time for assembly without any panic.
What to order in this window:
- Crib or cot with mattress
- Changing table or dresser with changing topper
- Nursing or feeding chair
- Wardrobe or storage unit
Weeks 19 to 24: Paint and Furniture Arrives
Paint the room now. Not in the third trimester. Painting while heavily pregnant is uncomfortable and the fumes from fresh paint need time to dissipate before the baby spends time in the room. Doing it now gives you weeks of ventilation before the baby arrives.
Choose paints with low VOC content where possible. Open windows during and after painting for as long as practical. Let the room air thoroughly before filling it with furniture and soft furnishings.
As furniture begins arriving, start the assembly. Do this together with your partner rather than alone. Flat-pack assembly when pregnant is awkward and often involves positions that are uncomfortable in the later weeks. Do it now while it is easier.
Once the main pieces are in place, begin arranging the room. Think functionally. The changing table needs to be within reach of nappies, wipes, and cream. The feeding chair needs enough clearance to sit comfortably and stand up easily. The crib should sit away from direct sunlight and away from any windows with cords or blinds.
Weeks 25 to 28: Details and Storage
The big pieces are in place. This is the window for everything that makes the room feel finished and functional.
Storage solutions, shelving, blackout blinds, and a baby monitor go in now. Wall art and decorative touches. A soft rug. A lamp with a dimmer for the overnight feeds when you do not want the overhead light on.
Stock the changing station at this stage: nappies in multiple sizes, wipes, barrier cream, and a spare outfit or two in the drawer beneath it. Set up the feeding area with whatever you will use during night feeds: a small table for a water bottle, your phone, and anything else you will want to hand.
Third Trimester: Finish, Wash, and Get Ready
By the time you reach week 28 and beyond, the nursery should be structurally complete. The third trimester is not for painting rooms or assembling furniture. It is for finishing touches and the final practical preparations.
Weeks 28 to 34: Final Touches
Add the remaining small details. Personalised items, photo frames, any artwork that was being made to order. Anything that was waiting on the gender reveal or the name decision.
Install the baby monitor if you have not already done so. Test it. Confirm the camera angle covers the crib properly and that the signal reaches your bedroom.
Check the room temperature. A thermometer in the nursery helps track the room’s baseline temperature across different times of day and different weather conditions.
Weeks 34 to 36: Wash Everything and Organise
This is the practical final step. Every item of clothing, every fitted sheet, every muslin cloth needs to go through a wash in fragrance-free, baby-safe laundry detergent before it touches your baby’s skin. Newborn skin is sensitive and fabric straight from packaging is not ready to wear.
Once everything is washed, organise by size. Label drawers or storage bins by age range: newborn, 0 to 3 months, 3 to 6 months. Having this organised before the birth means that at 2am when your baby has just sized out of something, you know exactly which drawer to go to.
Do a final check of the room at week 36. By this point the nursery should be completely ready. Not mostly ready. Completely ready. Your baby may arrive before your due date and the nursery being done means one less thing to think about when everything else is happening.
If You Are Working With a Small Space
Not every family has a dedicated nursery room and that is fine. A corner of the main bedroom or a shared room works just as well with the right approach.
A bedside bassinet takes up significantly less space than a full crib and is ideal for the first months when the baby sleeps in your room anyway. A compact dresser with a changing mat on top replaces a separate changing table. Wall-mounted shelving keeps storage off the floor. A compact nursing chair or even a well-positioned armchair does the same job as a dedicated glider.
The nursery does not need to be a separate room to work well. It needs to be organised, functional, and ready before the baby arrives.

Wrapping It Up
Start thinking in the first trimester. Start doing in the second. Finish and organise in the third.
By 36 weeks the room should be washed, stocked, and ready. Not because your baby will necessarily sleep in it immediately, but because being ready is one less thing to carry into the final stretch.
You built this for them. It will be the first room they ever know. Take your time with it and enjoy the process.
