This is great advice. In our case, we realized we can't trust our memory anymore, it became hard to remember who done it the most.

We wanted both a system that keeps track of it for us. We want to be sure we can both have activities while still not leaving the other parent on the side and rely on feeling.

In our case we also have recurring events like sport in the evening that happens every week at the same time so this help plan around it and not become unbalanced. We already put everything in the calendar :)
