Can I start using a larger-sized SleepSack™ wearable blanket on my newborn and then he/she can just grow into it?
We DO NOT recommend using a SleepSack™ wearable blanket that does not correspond to your baby’s current size. The purpose of the wearable blanket is to keep your baby from having any excess material that may bunch up around the baby’s nose or mouth. If the baby is wearing a wearable blanket that is too large, there is a potential for the baby to slip through the neck hole or bunch up the excess material around his or her face, potentially causing the baby to re-breathe their own carbon dioxide.
