Whats a good nightime routine for babies?

I don't think you want to bathe him every night and a routine may be hard to stick to especially at that age. I mean you'll have to play it by ear cause they can do all sorts of things at that age. I have two and they are older than yours (congrats by the way and he is very cute!) and I've got a good routine with them (single parent) but even then it changes sometimes. But hey, try to get him on yuor schedule and see if he'll co-operate, if so, cool. Otherwise you'll have to dance to the beat of his drum until he's a little older. Good luck and happy baby night time!
