If you can't carry it - don't bring it! ;-)
So. Book bags. Rucksacks. Bag for Life. It's not the material. It's more, with bags comes lots of additional unnecessary STUFF. And we are trying to reduce STUFF. Bag for Life was only a suggestion - if your child can carry what they need in their hands and use no bag - even better.
Help us try and keep school as safe an environment as possible. If they can't carry it - don't bring it ;-)
Bring what you need and nothing else. If children have a rucksack, they tend to try and fill it - pencil cases, toys, additional books, P.E kits, jumpers, headphones, notebooks etc.
The less in school, the better. Hope this clears up any confusion.
