Math, if your last sentence is true, then I'm hardly surprised that people don't want to engage in such a programme.
The problem I think with a lot of 'help' is that schemes are rarely individualised to the families, and too tick boxy.
As MrsD says, there are things that are considered 'common sense' that a parent might be encouraged to do that are really not essentials.
My limited involvement with such agencies had me being told that heating the kitchen with an electric oven was a fire risk and that if I wasn't aware of that then they had grave concerns for my parenting. My 'intelligence' enabled me to get a letter from the fire brigade to send to them saying that it was an expensive way to heat a house but not a dangerous one.
I received no appology for that gross allegation.
I was also told that my child should not be wearing sandals in the rain in august, should always wear vests, should open my post the day it came, should attend the local sure start centre daily with one child and take up my free nursery hours with the second. What I actually NEEDED was for someone to look after my baby for a few hours a week so that I could get on with all the therapy that my SN child NEEDED which was impossible for me to do. But that would have had a financial implication.
I could not afford a new boiler because of the amount of money I was shelling out on childcare for my dd in order to work to private SALT targets (was on a waiting list of a year for NHS SALT) and then further expert advice and a small amount of tutoring. We eventually also sold our house to pay for ds' therapy, losing our security and home.
So, unless the 'help' is relevant to the family, and at least involves them and values their priorities and concerns, it won't be accepted.
My concern and priority was DS. He was 3, and rapidly moving out of his 'window of opportunity'. No-one wanted to help us. Which is why I think that SW was extremely out of order for quoting window of opportunity as justification for removing toby. As a SW you cannot use evidence and research to fulfil your own agenda whilst ignoring it when it suits you.
