Escuse me, however my son was a preemie (3lbs) and has immaturity issues which lead him to be belligerent. Which the schools tried to pass off as ADHD which he does not have. He is currently in the lower 10 percentile in weight height and development which leads to this immaturity.
He is disciplined however his growth levels (milestones) are way behind which is being addressed as always.
I am glad the boys you know have never talked back or acted as if they knew everything, questioning everything ect.
Good for you.
Both my kids were preemies (the one they insisted needed Ritalin weighed 2 lbs 9 ounces.) My main reason for not putting him on Ritalin (before I learned all the other negatives) was that it can cause weight loss. My son is finally catching up with his height and weight, but when he was in 3rd grade the last thing he needed was to have his growth further stunted. He was perpetually the shortest and thinnest kid in his class. (His height and weight were proportionate, but he always looked about a grade or two younger than he really was until he hit middle school.)
