I wasn't being hostile gator. It was a genuine question :)
There is also the question of why a family would/should be expected to beat the costs on behalf of the birth family and the local authority.
I could give you an example
In one day we had to pack a bag with enough milk and several changes of clothes.
Take baby across London
Find parking for several hours
Wait then take baby home.
That was a pretty simple, uncomplicated day.
We had to pay for the milk
We had bought the clothes
Petrol
London parking
Four hours waiting around
Then when we got home the bag would have several unopened but unusable bottles of milk and the others would be missing.
Nappies would be used.
Baby changed into new outfit and several items 'lost' ie babygros, socks, tops, hat, suncream, etc
So petrol, parking, nappies, milk, replacement milk, replacement bottles, replacement clothes.
Baby had four of thse contacts a week for 18 months.
Plus the reviews, clinic and hospital appointments and social worker visits.
It cost a lot of money. But I am honestly not being in anyway hostile. Just sharing an experience ;)
