Even though most plastic bottles are BPA free now, there are other substances leaching from plastic into food and drinks contained in plastics. Since the single, most highly consumed item is water, I considered switching the kids’ water bottles to the ones made of metal.
It wasn’t very practical because both kids and teachers were unable to look into the bottle to see how much water has been drank. Kids being kids, they forget to drink water, and seeing a bottle full of water helps both teachers and kids to push for it. In addition, metallic water bottles also tend to be much heavier.

I decided to continue letting the kids use plastic water bottles for practical reasons, but stick to non-plastic unbreakables as much as I can when they’re home.

These cups are a little smaller than what I’d like, but they’re my favourite among the brands I’ve tried.
