Toddler weight worries

[MummyG17]

Hi all,

My DS is 27 months and weighs 15.6kg and is 87cm tall. The BMI calculator says he's very overweight. I try really hard to keep his meal healthy and portion sizes small. I think it's his activity levels which are causing him to put weight on. He's being treated for asthma with several medications and although we've seen an improvement he's still not as active as other children his age. Any advice?

Why isn't he active? Can't you take him to lots of parks etc - get him out and about on his feet as much as possible?

Presumably he’s less active because of his asthma? I’d be worried being overweight might make his asthma worse...not sure if this is an issue or not?
