rickman, this is no reflection on you as a mother, nor is it anything to be ashamed of or worried about IMO.
It is actually refreshing to hear of a school supporting their pupils so well - I spent many years trying to get support from my two children in school, to no avail!
You sound like a lovely mum, who's concerned about the welfare and education of her children.
Please don't be worried or upset by this - it is a positive thing for your children to be given a bit of extra support if that is what will help them feel happier and more confident at school.
