My 20 month old usually is a good sleeper she used to sleep right through up until about 2 months ago, now she gets up between 1am and 3am every night and is awake for about 2 hours. She is in her own room and own bed she only has 1 nap in the day about lunch time for an hour.
Does anyone have any suggestions on how to break this habit and get her to sleep through again ?
Thanks
