💡 Sizing Tips for Parents
Weight Over Age
Always use your baby's weight as the primary guide. Age ranges are just estimates.
When in Doubt, Size Up
Babies grow fast! If between sizes, choose larger. They'll grow into it.
Account for Shrinkage
100% cotton shrinks 3-5% after washing. Factor this in for fitted items.
Consider Body Type
Chunky babies may need to size up. Long babies might need longer lengths.
