My 4.5 month old daughter has been a great sleeper until about a month ago, but suddenly started aking every hour after 1.00 am. She feeds well an has a dream feed, have even started her on solids this week as I felt she was hungry to na avail!! Have decided now that she can't settle herself bach to a deep sleep after losing her dummy. Any suggestions?My husband and I are both done in. Is cold turkey the only way with getting rid of the dummy?
