N.D.
All my infants wore nightgowns with mittens built into the sleeves. I give them to my children for my grandbabies also. They keep baby warmer, are easier to change diapers, let the baby squirm around and above all have the built in mittens. As for him being limp that is normal and I used to love playing with their floppy arms and legs when they were in a deep sleep. Its so cute.
