My 14 week old will have her bottle and go into her crib half asleep she will then sleep for around 1hour then Is wide awake again for another 2 hours plus. She will also happily lay in her crib for this 2 hours aslong as someone’s in the room. I’ve tried changing her bed times back and forth but will always wake after an hour. Any advice on keeping her asleep she gets far too over tired once awake.
