Hi all. So my 6 month old has Been waking up between 1-3 am the last week. She usually goes to bed between 9-10 pm. She’s not hungry. As soon as we pick her up she instantly falls back asleep and as soon as we lay her down in her crib she starts crying. And we repeat the process until we eventually feed her. She used to sleep better before this. Any idea what could be going on ? She will Than do it again in 3 hours. She gets all her ounces in during the day. She’s not sleep trained yet but she knows when it’s bed time.
