My baby is going to be 4 months on the 4th. She did go to bed At 10:30 every night since she was like 1 month old. She sleeps for 12 hours regardless what time she goes to bed. After she wakes up I give her a bottle and she stays up for about an hour or so and takes a nap, and that cycle repeats till around 7 pm and she stays up till around 9 and takes a nap then now hasn't been sleeping till like almost 1 in the morning. She always has a bottle before bed so I give her one but she just crys from like 9 till whenever she decides to sleep and honestly it's making me go nuts at night. I get real depressed and angry and I want to just walk out I'm super tired and idk what to do.
