Baby clothing sizing
What size — and what to actually buy?
By age, with weight + height ranges that brands actually use. Plus honest notes on which sizes are worth stocking and which to skip.

H&M sometimes skips and pairs as 4-6m or 2-4m.
Carter's, Old Navy, H&M, Gap, and Target's Cat & Jack all overlap on these size-by-age ranges within an inch or two. The bigger variation is between cuts (regular, husky, slim) and between countries (US "12mo" runs slightly smaller than EU "74cm").
Buy by weight, not month label. A chunky 4-month-old often needs 6-9mo; a petite 9-month-old may still wear 3-6mo. The clothing tag's lower bound usually matters more than the upper.
