For about 2wks now my 16mth old daughter has been waking at around 4.30-5am every morning, had no problems before she normally went from 7.30pm-6.30/7am. Previously if she did wake she would just do a bit of a moany cry, her musical thing would be set off & she would soon go back off to sleep but now she stands up in her cot screaming her head off until one of us goes in. We have realised over last couple of days to just get her out, change nappy & put her back in cot, leave the room and she eventually goes back to sleep without crying (as before we were bringing her into our bed but didn't want her to get used to this!). Don't think it's because of nappy as not always full. Any suggestions would be very much appreciated. p.s. put her to bed hour later last night but made no difference....!
