A medical diagnosis is different than watching many kids for several years all in the same age group and seeing that there are some kids that can't ever settle down and focus.

My son has ADHD. I remember when he was that age all the other kids would be napping peacefully and he would be sectioned off in the house area with the teacher while he spent 2 hours twirling around with his blanket while the teacher begged him to be quiet and not wake the others.

I didn't het him diagnosed until he was in 5th grade but I could tell, looking back, while I was pregnant that he was different than his twin sister. He moved constantly.

I can tell now with my many years of experience after 3 or 4 minutes which kids have it with a really high accuracy.

However its very difficult for the parents to see it in their kids for 2 reasons. 1. They don't have those mutiple experiences with the many kids that teachers have in a controlled environment (like having 30 kids try and cut with scissors and there is that 1 that you snow will swing them around) and 2. They have trouble admitting that their kid isn't perfect. ADHD is a life long genetic disorder that comes with stigma and often shame and misunderstanding that ts the parents, especially the mothers fault. So it gets hidden and ignored. Which is sad, because there are a lot of meds that can be game changers and its sad to watch those kids, whose parents are in denial, suffer long-term. Kids who could have friends and good days at school and family dinners and star stickers on their homework never have those experience.
