After getting an email from school saying they were tightening up their security it struck me that up to now it's been a fairly trusting place. It's a junior school so most kids go in by themselves. I sometimes help my yr3 dd with her giant sports bag but usually she manages. However the rule is to now sign in a reception and get a visitor badge if you want to help your child into school with their things. They have also stopped parents speaking to teachers for a word in the mornings. A request for an appointment now has to be made via the school office. Again I totally get why there is the need for this but if you just wanted to let the teacher know something reasonably trivial it's going to irrelevant by the time they get the message!
How approachable are your teachers and school generally?
