This is a set of 3 maternity pajamas. I received two of them from another seller (with nursing access) and wore them during my pregnancy last winter. They show some signs of wear and tear from being worn. The navy blue one was purchased at Birthday last winter and has only been worn 3 or 4 times (with pockets, no nursing access). Please understand that these are not new. All are size L. Would these be suitable for someone expecting a baby in the coming cold season?
