I have always been really happy with the care DD, 12 mths, has had at nursery but something happened yesterday that really alarmed me. Her fantastic keyworker is leaving which we are very sad about and a new girl, who we don't really know very well yet, has started doing handover. Yesterday I got there to find that DD had taken a fall head first off the changing table onto the floor and had a huge bump on her head. Apparently her new keyworker had turned round to pick another child up and DD had launched herself off the changer on to the floor. Now, I know accidents do happen but I really don't think something like this should ever happen. Its a first and basic rule that you never leave a baby unattended on a changer, even for a second, and I am really worried that this new girl might just be really inexperienced. Everyone looked very worried when I got there but at the time I didn't want to make a big deal of it in front of DD and the other babies but have since been wondering whether this is something I should take up with the management. Any thoughts as to how to handle this?
