It's awful - poor child. Debih, I so agree that children shouldn't start until 6 or so. That's the age both in SA and in Germany to start school - with leeway one year either side depending on a child's abilities and maturity.
As for the schools not allowed to comfort / cuddle - too sad. I remember at the school where T & A were (well A is still there), a child wet his trousers once and was too distraught to get himself sorted so they had to call the parent. Poor child sat like that until the mom arrived because the teachers weren't allowed to do anything. They provided blankets and towels, but weren't allowed to help him undress
It must be so hard for a teacher as well though if you think about it - what they want to do and what the law allows them to?
