help! FTM! how do I establish a schedule?!

Kara
Hi mamas and dads! My son is almost 3 months old and I need to figure out how to get a schedule going. We go to bed anywhere from 7-8 and do baths on Tuesday and saturdays. He's normally up at 2-3 am to eat then sleeps until 6-7 but lately he's. Even up at 5 and stirring way before then. He sleeps in a bassinet in our room for now. So I normally feed him then sit him on my chest for a half hour then put him down. I want to transition to his crib soon . I was thinking of starting with napa in the crib to get him used to it. Does anyone have suggestions or care to share your routines? I'd so appreciate it! Thank you!
