Is your baby sleeping all night?

My husband constantly says things like “why can’t he just sleep all night like other babies” and will name off people who’s babies are supposedly sleeping all night and have been since they came home from the hospital. I told him those babies are the exception, not the rule. He still thinks that at 9 weeks he should already be sleeping all night long. I told him he’s insane. I have a 10 year old also so this isn’t my first rodeo. So I’m making this poll to prove to him that MOST babies do not sleep all night until they are more like 4-6 months old and maybe not even then, just depends on the baby.
