BALLOONS
This is a tricky one. Kids LOVE balloons. But there are lots of decoration alternatives, like buying some upcycled bunting from eBay or Etsy. You can also get lovely paper pompoms that you can hang from ceilings or chairs. And you can still play that game where you bob them around the room without letting them touching the floor. If you simply can’t do without balloons, check out Little Cherry who sell biodegradable ones in all shapes and sizes.
If you do buy biodegradable balloons, please, please don’t release them. They end up in rivers, the sea and hedgerows when they eventually pop, and can seriously harm wildlife. They need to be disposed of properly, either in your black bin or in the compost heap.
