I sent my 12 month old to my dads for the night and him and his girlfriend kept telling me I shouldn’t be putting him in the sleep sack anymore. That it’s mean. That the baby doesn’t like it.

Am I wrong for doing this? We’ve used one since birth! I feel safe with it! Plus my son kicks and moves a lot in his sleep, so if I have him a blanket, he would for sure kick it off and be cold at night. He doesn’t seem to hate it either? They said that because when they were putting him in it he was crying, but he’s a baby...they don’t like getting changed?

Idk I think they’re crazy, they think I’m crazy...lmao thoughts?
