My problem with it is that they weigh your child and you get sent a letter and that is the end of it
It's not the end of it in my area!
DS was weighed before school closed down as part of the year six screening programme. We knew he was overweight and this is due to medical reasons, his weight was being monitored by his paediatric team so when the permission slips came out from school I ticked the box to say that I did not give my permission and I did not want him weighed. It turns a out that despite what you tick o the form, they ask the child on the day and go with whatever their answer is.
So we got a letter saying he is overweight which we ignored.
A few days later we got a phone call from the child health team to discuss it and ti offer DS a place on a healthy eating course, usually done in person but currently being done by video link. Three sessions, each an hour long, around healthy eating, making good choices, and getting exercise. I explained told the person on the phone that the call was appreciated but none of that is applicable to DS, it is not something he is able to engage with, and that it's all in hand so thanks but no thanks.
A few days later I got a letter reminding us that DS is overweight and repeating the offer of the video course.
A few days after that we got another phone call stating that DS "has to go on the course" and that they take a dim view of parents who are unwilling to engage with it.
DS paediatrician has said to ignore it.
