My son is almost three years old and his daycare teachers and my family seem to think he has ADHD. As I child, I had ADD and I know that it is a serious issue. He has already been kicked out of one daycare and right now he is on probation at the new one. The teacher says that he is aggressive, hitting, punching, kicking, biting, and pinching. He also talks back to her and rolls his eyes already. He is a really bright child and the teachers do agree with that. He knows his alphabet and can recognize most letters and numbers which is better than most of his class. However, they can not move him up into a higher level class because of his behavior. Lately, this has transferred into our home. He does not listen and he even hits me and my mom. His dad and I do not believe in spanking, but lately I find myself wishing we did. I do not know what else to do. I am a student in college and I am getting called every few days to pick him up because of his behavior. Is it possible for a three year old to have ADHD? I am at my wits end. If it is possible, what can be done to treat this and how will it affect my son. Another problem is that he is only 34.6 lbs. He eats, but he is so hyperactive that the weight is gone instantly. I can hardly get him to sit down and eat. I can not find clothes to fit him this winter because he is so tall, but so skinny. He should be wearing a 4T, but his waist is so small that a 2T will fit but is too short. I just don't know what to do. I don't really want to spank my child nor do I want him on medicine, but I do not know what to do anymore and neither does his dad, my fiance. Help!!
