Hi, my nearly 11 month old used to reliably have 2 naps a day but recently has started to fight her afternoon nap. She has a morning nap roughly 10-11.15 and then I put her down for her afternoon nap around 2.30, but recently she just chats, rolls around and won't go to sleep. She can do this for up to an hour and a half in her cot, by which time it's too late for a nap. Then she's a nightmare at bedtime and wakes loads in the night because she's overtired. This has been going on nearly two weeks now, with this happening about half the time. Is this just a phase? Does anyone have any advice? Thanks 😊
