Hope she heal quickly mate. Its that horrible feeling you get in the stomach when you hear them in pain that always gets me.
My youngest (who was 5 at the time) was playing next door with their grandson when the grandmother brought her back round screaming her head off. Her right hand was rapped in a blood covered tea towel. It turns out they were playing with some solid concrete animal garden ornaments and she dropped one on her thumb.
It split the nail across, so we took her to A&E where they cleaned it up and dressed it.
The dressing was meant to be one that does not stick to the wound but for some reason it did. So the next day I took her to A&E to get it sorted as it was giving her a lot of pain.
They soaked it and then started to take it off. All i remember was her stood there with tears streaming down her face saying 'ow, ow' but not budging her hand one bit. That was when I realised my little 5 year old was harder than me!
I would have struggled to stay still for that and her older sister would no have made it to the hospital she would have got that worked up at the thought of it!
Her injury was no where near as serious as your daughters but it just goes to show how resilient they are!
Good luck with the recovery mate
