Hello B.,
My daughter is 7 months old and her sleeping habits have recently changed too, although we don't feed her a bottle in the middle of the night. She has been sleeping through the night since 8 weeks old, but the last couple of months she has been waking up several times a night. She will get fussy but after we give her the pacifier she goes back to sleep. We took her to the doctor thinking it might be an ear infection, but that was not the case. Her ears looked fine. The doctor thinks it might be due to teething...two of her bottom teeth have finally came through. We've been giving her infant tylenol as needed, especially before bedtime. Hope this information helps!
