Hi OP. Wow you are getting a bit of a slaughtering here, and I don't think that is fair. I am wondering if the Citizens Advice Bureau would be of any help to you if you are a single parent?
Because it might be that it would be better in your case if you didn't have the tax credits, but somethig like universal credit instead?
Ask the CAB if they have any of their volunteers who know about the different types of benefit - I am pretty certain that they must do, and then make an appointment with them, because if your approx £16,000 per annum is your sole income apart from child benefit, then it does seem as though you should be entitled to more than that. If you haven't got any regular money from your child's father and that isn't because he isn't named on your child's birth certificate (for whatever reason), and it isn't because he sadly died, then they might be able to point you in the right directions to get that sorted out too. It can't hurt to ask them as sometimes we think we know something, but it is outdated knowledge, or there were other conditions about it that we are just not aware of.
I do think that as a first world country it is disgusting that such things as food banks are even necessary, that not everyone has a roof over their head, that NHS hospitals should have to depend on charity for things like neonatal care equipment and scanners etc, that parents can't even afford to take a train to take their city child out into the countryside to see cows and sheep in fields, that schools are not funded for enrichment days out for their pupils to eg visit a farm to see cows being milked, visit a postal sorting office - we did that when I was a junior school child (1960s), and I found it very interesting - my parents didn't have to pay for that, or for when we visited a museum in the next town. I think that parents should be able to afford to take their
child/ren on a day out occassionally, even if they have a low wage coming into the household, but maybe by using some sort of vouchers, so that the selfish parents who would spend that money on cigarettes or alcohol, don't have that choice.
If people are struggling, even when they have a wage, then
maybe things like breakfast and after-school clubs should be subsidised for those who need them, but do not qualify for them being free.
