Height and weight centile question.

[Harleyisme]

If a cholsd always been around the 98th centile for weight and between the 50th and 75th centile for height since they have been born is this really over weight or there build?

Our health visitor said of our DD, that as long as she kept more or less to her centiles (I think 91st for weight & 75th for height) she was fine. Apparently it's if the start to go up on the weight centile compared to the height, that it can indicate a weight "issue". It has eventually evened out, & she's on 91st for both now.

Got a letter saying my ds is very over weight. Hes 5 and been around the same centiles since birth between 50th and 75th for height and either just under or just above the weight one but it never flucrates more than that.
