TLE I wasn't specifically talking about your child at all and I haven't looked at his photo. What I'm trying to say (and I accept I'm not doing it well!) is if, for instance, your child is "obese" according to the chart, yet is 3 and fits 3 year old clothes, and doesn't look fat, there's enough anecdotal evidence "against" the chart that you can not worry.
If you however have a child who is obese on the chart and is also wearing much bigger clothes (I know the tallness thing skews this but like I said I'm not talking about specific examples but generally speaking) and is weighing a lot more than his peers, even if he doesn't look fat to you, you might consider that the child might actually be carrying a little extra fat, possibly more than they should be enough to investigate further.
I'm in this boat myself in that my 3 year old was born at 98th centile and followed it into his 2nd year, is now 91st centile and only borderline on the chart for not being overweight.
He wears size 3 clothes, doesn't look fat to me or other family members or the friends I've asked though I would take that with a grain of salt as they probably wouldn't want to offend me, or his health visitor who was surprised he weighed as much as he did. Because he's in size 3 clothes and doesn't look fat, I can probably assume he's a bit stocky but I will watch his weight (without him realising I'm doing so) as he probably has a slight tendency to be on the heavier side.
I suppose what I'm saying is if I didn't keep that level head about it and analyse it from a chart perspective, I would have just said "he's fine, he's fine" and probably would not have taken the measures I did to get him down to the 91st centile. He might be obese by now.
Or not!
It doesn't matter, its a worthy debate because I think one of the factors in the childhood obesity debate is (a) are parents really able to judge or to they have their love heart shaped frame glasses on and (b) are the NHS charts too tough, too unrealistic, or a pretty good general idea that things might be heading in the wrong direction, and is there a better way to measure, and if so, what?
I too think the charts are in a sense outragous for making my child borderline but I remind myself that its not about looks but about health, and if he's heavy enough on his feet that it makes him not want to be active then we'd be heading in a bad spiral. As it turns out I can't slow him down so I dont have anything to worry about at this stage.
Its all worth debating though, I partly regret singling you out like that so please accept my apologies.
