Gerber Toddler Snug Fit Cotton Pants Set Pajamas, 4-Piece, Sizes12M-5T

My baby is only two and a half months old and I bought these size 12 pajamas to prepare for the future and it turns out that I already had to put them on because if they are too small, my baby is neither fat nor big, I don't understand what happened! because the size 12 clothes I bought don't fit yet.

Low colors perfecto steeves genal la talla corresponde su color es el mismo y llegaron rápido el material increíble pedi en talla 5 poq no había mas para mi hijo de 2 años y como el es gordito y grande si le quedó cabe recalcar qué las pijamas vienen al cuerpo recomiendo pedir una talla mas o 2 sleeves
