Does this matter? My son had his reception weight and height plotted by the school nurse. I checked his BMI from their measurements and he came back as overweight. He definitely isnt, you can see his ribs and his 4-5 trousers fall down on him. So I rechecked his measurements at home, and allowing for individual discrepancies, it seems they've written his height down as 102 cm when he's actually 112. Based on these measurements he's on the 12th centile, rather than the 93rd. Would you contact them and ask them to adjust his records? For context, I'm obese, and am very anxious about weight. I work really hard to ensure my kids have a healthy diet and lots of exercise, so I appreciate I might be being excessive about this. I don't want him officially recording as being overweight when he's not. I don't know what happens with the records though. Does anyone know?
