dd is 11 mths and used to go to sleep relatively easily in the evenings - 'til 2 weeks ago when she learnt how to sit herself up. problem is she can't lay herself back down and ends up getting herself in a right old state. each time we go in we lie her down, say sleepy time and leave - all in the dark. she keeps on doing it though - tonight we're on visit no. 8 so far. then we end up either bringing her downstairs to calm down or i give in and feed her (bf). i know this is just a phase but how long has it lasted for others? and any tips on what to do. i'm finding it really stressful. it's also been the case for daytime sleeps as well. she's also just starting to want to stand up with help - so i guess it'll be that once we get over this will it??????
