My mother in law is wonderful and helps us out a lot by having my dd for an hour after school, till I can pick her up after work. However, the last two times I have collected her. dd has been playing with some other little girls outside the house (it is a cul de sac) and MIL and PIL have been inside the house, doors closed, clearly not watching dd at all.
DD is just 5. Clearly the other little girls are allowed to play out too and they are a similar age to mine. However I am not entirely comfortable with a 5 year old playing out unsupervised. It is a quiet road and MIL would see dd is she glanced out of her kitchen window, but she was sat in her conservatory at the back of the house when I arrived today and didn't seem to be watching dd at all. She didn't even realise I had arrived until I walked into the house through the back door.
Am I unreasonable to ask MIL to supervise dd if she allows her to play outside?
