When I was 0 months old, I rotated between the set of short undergarments and combination undergarments. From 1 month old, I switched to rompers. Snap-type for easy and time-saving. Made of 100% cotton knit fabric, it can be used all season. To avoid direct contact with the baby's skin, the seams of the cuffs and hems are on the outside. This is a set of two assorted design combination undergarments with a slightly longer length that wraps the body firmly. It features an M-shaped design that fits the baby's legs, so it doesn't cause stress when worn. It also has snap buttons at the hem, preventing it from riding up and keeping the tummy warm. It's a great item that absorbs sweat while also providing warmth. Comes with a name tag.
