How can i get my 4 week old baby into a nap schedule?

shes 4 weeks old and sleeps during the day but not all day. she has about 3-4 different nap times but she falls asleep on her own and only in her bouncer. if u movs her to a binet she wakes up. but at night sleeps in binet we want to transition her into a crib and was wondering what the best way to do that was starting her out trying in the crib for nap times during the day??? at night she wakes up 2 but mostly 3 times a night and sometimes doesnt make it through bottle before shes out again? any ideas?
