please help my crystal baby

I have a 3 month old baby girl who I believe is a crystal child. My two older children (both boys) ages 12&16 are indigos. My sweet little angel has what appears to be insomnia. I believe she is having dreams of her past life and is afraid to go to sleep. She is also teething badly and she is early for that also. She will be awake for as much as 18 hours sometimes. Her little eyes are red and I can see she really needs to sleep but fights it. If I am able to get her asleep she will wake herself up in 15 minutes or the minute I set her down. I tried sleeping with her.. she still wakes up. I tried meditating with her... I have prayed and asked angels to help. I am begging for any insight or ideas. Namaste
