5 pairs of back zip pajamas, size 5T, awesome for kids that undress themselves / kids with disabilities. 3 pairs of the Little Sleeper Keeper escape-proof back zip pajamas (shorty style) and 2 pairs of Old Navy that are technically front zip but we used as back zip. Our son is autistic and would undress at night, and back zip pajamas were the only way to keep him clothed (and avoid some… potential messes). The Little Keeper Sleepers have an additional layer of security with a series of snaps over the zipper pulls (second photo). The shorty style is short sleeves and knee length (or slightly past). Smoke free, pet free home.
