DS14 shares a lift to school with two other friends in his class/bubble with one parent driving. Not ideal but they are in a bubble together anyway. Another child who is not in their class/bubble or sharing a household with them is now going to start lift sharing too. I feel much more uncomfortable with this as another bubble is being introduced into the mix. In an enclosed space. Should I end the arrangement for my DS? It feels like the right thing to do but he is going to be so angry about it. WWYD?
