DC2 is 6 weeks and doesn’t sleep for the night until 10-11 PM. I feel like DC1 was already sleeping by 8-9 PM by this age. But possible I’m misremembering 
DC1 is 2yrs old and in bed by 7:45. Ideally I’d have both kids down by this time.
So will the baby’s earlier bedtime emerge naturally soon? Or do I have a night owl on my hands?
