Is there a 9 month sleep regression?!?

Dawn

My girl was born on May 1st and almost since the time we brought her home she has slept thru the night (we’ve been lucky)! If she ever did wake during the night, which would happen from time to time, she would only wake once, eat and then go back to sleep. Well as of the last 3 weeks or so she seems to wake up almost nightly between 1 and 4am. We usually will give her a bottle and she will go back to sleep. However, this worries me because I don’t want her to get used to that nightly feed to go back to sleep as we will be taking the bottle away in the next few months as she reaches a year old. Has anyone else had this lately? I’ve heard of a 4 month sleep regression but never 9 month. I sometimes think maybe she isn’t getting enough calories during the day and then wants them at night but she is already 95th percentile for height and weight and weighs in at 22lbs! Idk how much more I can give her. She drinks roughly 28 ounces a day. Has cereal for breakfast, a container of baby food for lunch and usually a container of baby food or some of whatever we are having for dinner.

Anyone have any suggestions?!?!
