DS (6 months) and I went to a settling-in session at the childminders last week. She had a 1 year old mindee there and two older ones who normally come after school but are there all day during the holidays. As the childminder was letting us in the front door the 1 year old crawled out of the back door and hurt herself as one of the older ones had left the back door open. The childminder had a word with the older child and said he said should know not to do that. The 1 year old was ok but I was pretty horrified. I imagine that accidents like this do happen, but what do you think? Should she have more safety measures in place? She really did seem to be the best childminder available and is very well thought of but I'm having doubts now.
