SueGHi Rebecca,
I was in your shoes not so long ago. It can be extremely overwhelming and I can fully identify with your not knowing if it’t a "baby thing or a CAH thing". AFter seven months I still get doubts sometimes. But believe me, it DOES get better. Slowly but surely you will learn what to watch out for and like everyone said, TRUST YOUR INSTINCTS.
Good luck and God Bless,
SueG
