It took an item on the Victoria Derbyshire programme to get the crisis in adoption onto the agenda.

They interviewed the dad in a family who'd sent an adopted child back into care, he said it was the worst decision he'd ever had to make.

The scale of the problem isn't revealed by numbers because, shockingly, there aren't any. There are estimates, they vary wildly; the BBC website reports that 3.2% to 9% of adoptions fail.

The charity Adoption UK thinks 25% of all adoptions are in crisis.

I'm thinking about this in its own right but also because adoption overlaps with fostering in many ways.

The majority of failed adoptions will be placed with us foster parents. We'll have to try where the adoption has failed. I use the word 'failed' reluctantly, because we all know what some children in care can be like. Indeed there are times when some are too much for fostering and children for whom that's the case end up in special care such as a unit.

But I wonder if the government are simply cutting too many corners with adoption. It appears to me that once the adoption goes through the family are pretty much on their own. In fostering we get support, ongoing training and supervision. If the child isn't settling there's expertise available, whether it works is another matter, but the point is we're not alone. I don't know more than the next person about adoption, but it looks pretty lonely compared to what we do.

If an adopted child is struggling there is government money available for therapy etc, but it's capped at £5000 per year, much less than the cost of fostering.

Money isn't everything, but it helps. Why can't there be bands of care for children?

Ultra Fostering - the most challenging cases; full-on-suppport and backup.

Fostering Regular - what we have now.

Fostering Light - for those children and young adults who are relatively maintenance-free.

Adoption Plus - for children who are wanted as full family members but have issues to iron out; intervention and support available.

Adoption Regular - for children who have settled as family.

I haven't done the sums, but with good management the system could get better results on the existing budget.
