That's it really. DD started reception class last week and all the children have made badges with their name and photo on. But rather than being stuck or pinned to the clothing, they are on long (60cm) strings to be worn round the neck. (These wouldn't give or snap if they were caught or twisted.)
AIBU to think this is dangerous with a group of 45 4 year olds and maybe 5 teachers/TAs? They are not allowed to wear them in the playground, but they are allowed into outside play areas and reception contains several rooms.
