From being around 8 wks to 16 months my daughter settled and slept through the nite no prob and was in a good routine, however, 7 months ago she suddenly started waking during the night,every night. She can wake up at any time and can be awake for 10 mins to 4 hours. Sometimes she whinges or cries and sometimes just mumbles to herself or shouts and screeches. Have made sure not too hot or cold, checked nappy, nothing scary in room, not too light. Usually there doesnt seem to be anything wrong with her and I think its just for attention. When she really is upset can tell cos of different cry. Have tried resettling her every 10 mins or so, have tried controlled crying, different nite lights, moving cot, stopping naps during day, stopped giving baby milk at night (in case she has too much energy) but nine times out of ten end up so tired and angry i scream and shout at her and shut myself in the living room with telly on (like a dazed zombie) so cant hear her until she eventually goes back to sleep. I know this is isnt the answer and feel so awful afterwards but tiredness just takes over and i snap especially as she still usually gets up at 7.30-8 after being up 4 hours in night. Feel like such a failure for not knowing what to do. Would like to return to full time work but feel this is impossible as my life is on hold until she sleeps properly. Am so completely run down and fed up really dont know what to do. Anybody, anywhere have any advice?? Please!!!!!
