My LO is 3 months old and she goes to bed around 7:30/8:00pm every night. Except after about 45 minutes she wakes up whining and if I give her a paci she goes right back to sleep. She will then wake up again a few more times (usually) between bedtime and 11pm. Then wakes up to eat around 2am and 6am. It's getting old and I'm not understanding why she keeps waking up. I've tried letting her cry for a few minutes but she seems to just get more upset.Any tips on how to break this?
