Is it normal?

So my baby weighed at 6lbs 12oz 19inchs when he was born and now hes two months and weighs 12lbs 23inchs . And when ppl see my son they say he's so big for his age or he doesn't look two months 😶😑😔 and that makes me upset it's like they are saying my kid is fat. He only has chubby cheeks .
