How to measure before choosing a size

Use current length and weight first; month labels are only a rough shopping shortcut.
For babies near the top of a range, size up for diaper room and quick growth.
Check head openings, snaps and footed-sleeper length because babies outgrow length quickly.
For baby shoes, measure foot length and leave gentle wiggle room rather than relying on age alone.
