My 14 week old has changed her sleeping pattern at night, we put her to bed at 7.30 and give her a df at 10.30 she would then sleep through to 4 or 5 in the morning. Over the last week or so she has been waking at 1 to 2 in the morning. She is bf and When I feed her at this time she is only feeding from 1 side when normally she will feed from both sides. During the day she normally has about 2 to 3 1 1/2 hours nap and feeds every 3 hours.
My question is should I try and get her back to sleep without feeding her as she should be going 8 hours now without a feed or should I feed her as I have been doing?
