How big are your babies?

I picked my son up from childcare the other day and was asked by an educator how big he was at birth because he’s so small now. To me he isn’t really that small, he’s almost 11 months old and weighs 9.7kg (21 lbs 6 oz) and is 77cm tall (30.3 inches). According to our child health nurse app that is 60th percentile for weight and 80th percentile for height. If he’s small, how big is average? 😂
