As of the last couple of weeks my dd has started dropping her arvo nap. She used to wake at 6am nap at 9am nap at 2pm and go to sleep for the night at 5:30-6pm. Now it's wake at 6am nap at 9am sleep for the night at 4:30pm??!! I try to make her have a nap at 2 and she just babbles away in her cot for an hour no sleep at all then by 4:30pm she's falling asleep so I put her down thinking it's going to be a nap and she's out cold all night? I'm struggling to change it she just won't! She's awake from 11am till 4:30!! Any ideas or just go with it?
