My dd is 20mo. Over the last 1.5 months she has become a nightmare. If I am around she constantly wants picking up, as soon as I put her down she screams, throws herself on the floor and in inconsolable. She used to go to bed at 8pm, i could put her in her cot awake and be fine. She now flatly refuses to go in cot, she has to lie on our bed and once she is asleep we then put her in her cot and she sleeps through. Problem now is that she never falls asleep until 9.30ish. If I say no to her about something we have another tantrum, it is really starting to get to me and I now dread going home after work, please help need some advice before I end up going mad.
