My 3 yr old used to be a fantastice sleeper, 13 hrs a night 2 hr nap but since I fell pregnant a year ago her sleep went downhill. She now gets up twice a night comes into my room I take her back to bed and she does go straight off but she does this twice a night and in between my 5 month old wakes for a feed so I'm getting a 2hr stretch of sleep at the most at a time. We are all tired and grumpy the next day and I'm at the end of my tether. Have tried reward charts, bribery, night lights etc. Does anyone have any ideas/tips ?
