Dd3 (5) was weighed at school the other day. I got a letter yesterday saying that at 108cm and 21kg she is "overweight". Now they probably weighed her in her boots and school jumper, but I weighed her this morning and she is 20.3kg which puts her into the healthy range. Now not only could this cause upset to parents (not me, I was sure she was healthy) but national statistics will have one more overweight child, when she is not, I am sure there will be others, as such a small amount of weight can make a big difference at that age.
