Should I worry about my DS's weight?

[MrsJuggler]

My 7.6yo DS is healthy, active and smart, tho a pretty sensitive lad. He's also becoming pretty chubby, esp around the waist, taking 10-11yo trousers - and is the biggest kid in his class, which singles him out for comments (he's tall too).
So far only a couple of kids have teased him (out of school) and the adults he was with (not me at the time) handled it brilliantly, knocking the teasers back politely but firmly & making sure DS wasn't upset.
DS loves to eat - really healthily, but also just a heck of a lot! and of course sweet stuff too, like most kids. Sometimes I wonder if he thinks it's all going to run out, so he has to get it whilst he can.
It's made a little harder by his dad (my ex) being less than stringent about what he eats - plus dad was a 'fat kid' (his words) when he was little in the 70's, and has always had a hang-up about it, he was bullied a lot....
FYI I've a 3.6yo plus DSS 17 & DSD 15.
So, what do you reckon I should do - nothing, it's not an issue, or something - but what?!?

Try getting DS to cooperate with you - he's old enough to negotiate with. He has probably had other comments out of your earshot and may want to be a bit slimmer. I'm sure you are aware that overweight children often become overweight and unhealthy adults. You are doing well with the healthy eating bit, but its usually quantity not quality which is the deciding factor. Cut down on the portions you give him, and substitute fruit etc for sugary treats. maybe a sweet a week as a treat should be his slogan. Increase his level of exercise, it vital.
Get the school nurse and maybe your gp practice nurse on board to give you and him a nudge in the right direction. Get his BMI done, though if he looks a bit on the chubby side, its going to be higher than it should be. You are aware of the problem and not in denial like some parents, so you've both got a good chance of success. Good luck

I think you can do a lot very tactfully without making it personal: like making sure there are not too many sweet things in the house, buying lots of fruit and eating it with him, planning healthy meals etc. You can always say it is about the whole family- but best if you don't have to say anything at all.
