My son is engaged and living with a girl who has a 3y/o son. She has him every other week and she is starting a new job and I will be keeping him. I am a 53y/o retired RN of 25 years and I have NEVER seen a child so badly behaved. This week he actually bit his mother hard enough to brake the skin and leave a bruise. The last 2 days he has deliberately gagged himself with his fingers and vomited everywhere....several times. He has not been diagnosed but has all the signs I have read about and I am also concerned about autism. He often screams at his mother. His mom and I get along well but I don't know how to approach her or even if I should. We all know how medling m-i-l's are viewed. This kid is one you don't even want to be around and I adore kids and am a really patient person. I need some input from you guys please!
