Hello! I'm new to this forum and so very thankful I found it! I could use all the help or advice anyone would care to share. I'm a stay at home mom of two. My daughter Madison is 9, and she is a wonderful, bright, sensitive, and sweet child. My son Mason is 4, and he is funny, sweet, active, and very bright. Mason is also disruptive, aggressive, violent, destructive, verbally abusive, and bossy. Mason has never been easy. He was a difficult pregnancy and delivered 5 wks. early. From the day I brought him home until he was almost 6 mnths. old, he never stopped crying. It wasn't colic, he just wouldn't stop crying. I slept sitting straight up in a chair with him in my arms until he was 4 mnths old. The only thing that seemed to soothe him is when he had a fistful of my hair that he could yank on. When Mason first began to walk, if I had my daughter on my lap, he would push her off. Or bite her, pull her hair. When he was 2 he began hitting and biting myself, my husband, and my daughter. He had uncontrollable tantrums. At 3 he threw a heavy metal cymbal at my daughter hitting her in the eye and requiring stitches. Not too long after he threw a brick at her head missing her by inches. He is now 4 and while the violence isn't quite as bad as it used to be he remains uncontrollable. He has broken mirrors, he spits, screams in your face, says horrible things. He calls his daddy moron, and every day hurts Madison. Madison's friends no longer want to come over to play because Mason threatens to hurt them. The other day he was riping handfuls of my daughter's hair out while we were driving 65 mph down the highway because he was mad that I wouldn't give him what he wanted. Most of the time to me Mason is loving, sweet, and funny. I have an easier time with him. It isn't until Maddie comes home from school or my husband comes home from work that the problems really start up. Mason attends nursery school 3 half days a week where he is wonderful. He gets along well with his classmates, and listens to his teachers. Other than being extremely hyper around extended family, he is well behaved twords them. Also Mason refuses to potty train, and exhibits some symptoms of Obsessive Compulsive Disorder (OCD). My brother has Obsessive Compulsive Disorder (OCD), so I am familiar with the symptoms. I am extremely sad for my little boy who just can't seem to help himself. I am sad for my daughter who seems to be fading away. She told me that she is happy until she has to come home after school. Mason's behavior is causing so much havoc in our family and everyone is suffering. I have talked to our pediatrician and she blows me off. She keeps talking about time outs and sibling rivalry. I am currently seeking a therapist for Mason but finding someone who specializes in young children has been difficult. Maddie has started counseling through her school. I want to thank anyone who takes the time to read this. I know it's a long one. Any advice or similar stories would be greatly appreciated. I'm almost positive Mason has ADHD (my mother, both brothers, aunt, and uncle have it), and probably ODD. Any opinions?
