She's been great at going down up until recently, but for the last couple of weeks I'll take her up to her cot, settle her, all will be calm for about 10 minutes then suddenly she flips and starts crying. She shares a room with ds (4.7) so I can't really do the controlled crying - have tried it with her before and she just doesn't give in anyway, just makes herself puke.
So, she'll come back downstairs and faff about for a while, before eventually crashing out on the sofa by about 10pm. She's sleeping in the cot for the rest of the night but I have heard her bashing around in it and waking at various times through the night, but she usually self settles.
She is quite tall for her age, but so was ds and he was in his cot until he was nearly 3!
Should I move her to a single bed? Toddler bed? dc3 is due in 9 weeks and I'm shattered - any advice appreciated.
