My 4mo sleeps well at night (10-12hours), goes down at about 9pm as she is just not tired before then. I have always fed her to sleep but for the last week or so she will have a feed, unlatch and scream and cry until she tired herself out. I have tried winding her, walking up and down, changing her position and nappy but she just seems to hate falling asleep. She is the same during the day with naps, she will not just fall asleep peacefully! Does anyone else's lo do this or does anyone have any advice on how to stop it - I hate to think she is going to bed so miserable!
