Since about 6 weeks old, my DD has only napped for 30 minutes at a time, 3-4 times a day. I assumed this would pass but she is now 5 months old and it's STILL happening. I can get her to sleep at home in her Sleepyhead, or out in her buggy, but every single time her eyes pop open after half an hour and that's her, done. Needless to say she is knackered again after an hour or so awake. It's driving me nuts. Does anyone have any good ideas on how to break this habit? (Weirdly, she can self-settle at night and only wakes once for a feed around 4am).
