What time does she go to bed and how long does she nap during the day ...possibly she wakes at 6am because she has energy and wants to play then .Children of 1 year old are 'cling' they need plenty of attention.I suggest some book reading will be good, and walks , get Dad involved playing games and having fun ..The screaming is her way of getting attention, maybe when she wakes give her a snack and something to play with ...I know its a tiring age for Moms ..it does go by so quickly ..good luck
Honestly, it sounds like she's just being 1 to me. None of this sounds unusual at all, at least not in my limited experience.
Thank you. You can tell im a first time mum.x
If she wakes up too early for you, put her to bed later. I found it was more comfortable for me to be up and about by the time my babies woke up. Mothers tell me that they wake early no matter what. I doubt that is true since I put all four of mine to bed late and they all woke late.
