My 7 month old baby girl had been into a settled routine of waking up once a night, around 0300 or 0400 then going back to sleep until around 0630. For the past week though she has fallen back into a pattern of waking up every 2hrs again like when she was a newborn, and she won't go back to sleep without nursing.
There hasn't been any change to her daily routine, and I don't think she's teething, as her behaviour during the day has not changed, and she sleeps fine during her naps.
Has anyone been through something similar? Any tips?
