Then that’s great! Don’t let anyone shame him for being skinny unless there are pressing health consequences.

Not latest, but prioritizing and promoting playing on their own.

My parents tried to get me to gain weight my entire life. It led to a pretty bad diet by the time I was living on my own and I only ever gained weight when I ate chicken burgers from meal hall literally every day.

Don’t focus on weight, just make sure he is healthy. It can lead to poor choices and insecurities down the road.
