I´m in the accident category!
We live in a country with hard cement floors no carpet DD has the balance of a mountain goat has done since she started walking.
Last year at summer school she feel over badly, huge cut to her knee which had to be dressed and the dressing changed ever day, red hands, ginormas bruises. The school didn´t even call us, over here that is a nothing! She has picked up hugged, comforted, her injuries cleaned and dressed. She was look after, it was an accident she fell going down concret steps.
In my hawk like care she has cut her head right by her eye, she has had bumps, brusies, she has fallen over and cut her hands. She is looked after and well cared for but she is just one of those kids (she gets it from me)
I have more broken bones than anyone could be bothered to count. I just was accident prone.
To be honest I would be more worried about a child that had never fallen over, in the care of anyone. A child that has had a few scaps and brusies has been aloud to enjoy their childhood. IF that child is well lookef after and the person in whos company it occured was shocked, felt bad etc. Then I think you can´t ask for anymore than that.
I´m sure you DH is just a bit of a worry wart, but it is still frustrating for you to be dealing with. He needs to try and let dd enjoy the exploration that childhood should be.
Reassure him that falls, bumps, cuts, scarps are part of childhood and that they can happen at anypoint with anyone.
