YANBU to want more details, I am very suspicious of these fundraisers.
But when dd2 had to be in and out of hospital for a while, it cost us a fortune.
I had to drive to Bristol, (1.5 hours) and be there for 7:30 am. So car and petrol costs, plus childcare/school run implications for the 2 kids at home while dh was working.
Also food and drink for me while out (took packed lunch, but needed cups of tea etc)
Also car parking. The hospital did have a system in place, if you could find a place in hospital car park, it only cost £3 per day. If not then it could cost £10 per day.
She was only in as a day patient. I have no idea how we would have done it as an in patient.
Well, in fact we did do it for 10 days when she was in. The kids and dh stayed with my mum who had to do school run etc. I had to buy all meals and drinks from cafe as I stayed in her room with her. Dh had to drive up to see us/bring other dcs so petrol/parking etc.
It is pretty expensive to have a child in hospital. Dd2 was 18 months when she started treatment. I wasn't back at work, and didn't return until she started school, because of her needs at the time. So knock on expense of extended SAHM.
