When do you put your baby in their crib in their room?

Stephanie

Our son is 11 weeks, I have two daughters 18&16 I always had them from day 1 sleep in their crib , with my son he’s slept in a dock a tot in a bassinet next to me in our room. His bedroom is diagonal from us and I have a baby monitor. My husband thinks he’s too young to put him in his crib I don’t think so ? Thoughts ?
