Is this bad??

My son turned two on August 4th, he's 36 pounds and one inch away from being 3 feet tall. His doctor of course wasn't concerned at all but people keep making smart little remarks about his weight? I thought his weight was normal considering he's a tall boy? Not to mention all the men on my side of the family and his Dads side (including his dad) are bigger build and either are or around 6 foot tall. I'm just one of those people that I let things people say bother me when I shouldn't.🙄
