My house, my rules, there is no way I am sharing quiet time with a child. Nap time is sacred to me. Also these children are sleeping in my children's bedrooms so they are not invited to get into the big kid stuff. I am not going to mention anything about putting the dcb in a sleep sack. he is safe, warm and best of all CONTAINED. It will not hurt him, if anything he will be cozy warm and sleep well.
