my 7 month old has never been great at self soothing at bedtime. used to take bottle, get very drowsy, put him down nd he'd fall asleep. suddenly bedtime is awful. he has gone off milk and no longer accepts bottle. so nothing to send him off. he hates being rocked in my arms while i'm sitting. wants me to hold him upright against my chest while i stand which is killing my lower back. also he light evenings are making it worse. anyone else going through the same???
