My 7 month old little girl has never slept through the night.We have tried everything it feels like and are almost at breaking point. We have had a bedtime routine for a while now and although she goes to sleep ok, its only a couple hours later she starts crying again. If you go in and settle her at this point she usually goes back to sleep but then it will happen again a couple hours later without us being able to settle her.She can scream for a good couple of hours. We have tried soothing her, leaving her to cry it out and nothing seems to work.Any ideas?
