Bed time for 3 month old

What time do you all out your babies to bed? My little one was staying up till 10 or 11 at night but then I read she should be going to bed much earlier so instead of giving her a nap at 7 I started giving her a bath at 6:30 then bed time at 7 which is fine, she just wakes up every 15 to 30 minutes till 10 or 11 which is the problem. I have to get up at 4 every morning so I'm barely getting any sleep... any advice ladies? What are your little one's sleep schedules like? Naps too
