Also, my family who wants to return had never given me a definite "yes" when they left, so that is why I went ahead with filling spots. They did keep sending their older son 1-3 times a week over the last six months of mat leave, on a casual basis. The issue is that they were living in my neighborhood but moved over the summer. Over the last few months they have hinted at maybe wanting to send both kids in September, but no definite yes or no. When I asked last week when E's last day would be, mom said 'oh I thought by sending him a few days a week we were guaranteeing spots'. Lesson learned here, always disscuss return clients and get it in writing!
