I’m wondering whether our four year old boy has ADHD. He has always been a tricky child. As a baby he was constantly crying or fussing. He started walking at the age of ten months and hasn’t stopped moving since. As a toddler, I could never leave him alone, he was always getting into trouble. Now, as a four year old, things are even more difficult. He only sleeps for short periods of time and won’t sit still for long, even to watch TV. Time outs don’t work. Whenever we put him in his room, he destroys it.
