Jilly:
Your son is 3 years old and is scratching his face enough to draw blood? You are NOT a bad mama!! You are doing preventative care by clipping and filing nails...
Does he scratch to draw blood or does he just scratch and blood is drawn?
I am wondering if he has an allergy that causes his face to itch...hence his scratching...or if it is now a habit?
My son, at age 9, STILL bites his nails - to the quick - URGH!! We remind him FREQUENTLY - hands out of the mouth....and we compliment him when we see no hands in the mouth. When we are watching a movie - I have him put socks over his hands so that he cannot chew his nails...
good luck!
