Baby layette calculator (0–12 months)
Numbers are a starting point for shopping and hand-me-downs — adjust for your home, daycare, and climate swings.
Planning numbers with Baby Layette Calculator — illustrative, not professional advice.
How to use this tool
- Choose the region that best matches where the baby will spend most time.
- Set the expected birth month and how often you plan to run laundry.
- Read the table as rough totals per age band; combine sizes (newborn vs 0–3) based on growth scans and shop returns.
- Copy or screenshot the table if useful — all calculations stay in your browser.
Typical use cases
- Build a first shopping list before a baby shower or hospital bag.
- Compare two birth months if your due date window spans seasons.
Limits & caveats
- Twins, preemies, and heavy spit-up or reflux can need more changes than the table suggests.
- Regional weather varies year to year; heatwaves or cold snaps are not predicted here.

Combines a coarse climate profile (tropical, temperate, or cold-biased) with hemisphere so summer and winter line up sensibly, then looks at which months the baby is 0–3, 3–6, 6–9, and 9–12 months old to nudge short vs long layers, sun hats, and warm hats.
