This is a pair of comfortable Grow With Me Reinforced Knee Leggings. This pair will fit sizes 3-12 months (and beyond). These leggings are a slim but generous fit. They have a double layer at the knees with extra stitching to help aid in durability.
This pair of pants features adjustable cuffs at the waist and ankles that can simply be folded up or down to extend the length of time your child can wear this piece.
If you are unsure or feel your child is in between sizes I would suggest you size down.
