If you take your child to a soft play centre, they have no legal obligation whatsoever to provide first aid if your child injures itself. This from the Environmental health and safety officer at my local council.
Thankfully though, most places would probably rush to assist you. I wont name names because that would be wrong but my child was injured in a soft play centre in Herne Bay and we were offered no assistance or first aid equipment, in terms of towels to stem blood flow etc, someone to calm me and my daughter down because i was quite frankly in an total panic. They couldnt even tell me where the local Minor injuries unit was.
I reported this to the local authorities and they have said that the only come back i have is to file a civil case, which i dont want to do, the accident wasn't their fault, but some concern would have been nice. They have upheld the complaint in terms of them sending feedback to the place but can take no action as they have acted within the law - surely this can't be right???
Apparently the responsibility lies with the parents! well yes, of course it does, but i don't carry a first aid box around with me - i had to go to the toilets to try and find something to stem the blood flow (my DD had bitten through her tongue) I amd incredulous that this is apparently OK.
