Sorry....
I have heard it said that children may think that their father does not care much if he is prepared to provide, I wasn't necessarily saying that you thought that.
Actually I disagree if an absent father wants to play games with financially supporting his children for whatever reason, then I believe that he is probably not being the best father that he can, as he is not putting the children first.
Again sorry to say that I disagree with your attitude that finances are between adults, obviously children should not be burdened with unnecessary worries, but surely children need to understand why they might not be able to have something or go on holidays like someone else does, or why you might have to make changes to your lives due to a reduction in income.
I certainly don't want people to just agree with me, I would like to get a range of views, that is why I asked. That of course does not mean that I can't then express that I might disagree with certain views, or question the thinking behind it to perhaps actually try to get a better understanding of why someone might think that.
And for the record, given my ex's circumstances, £5 per week for 2 children is inadequate full stop, its not my opinion, that is based on his sudden claim that he rents a house, pays his bills, buys his food, fuel etc, pays into a pension, on his earnings of only £88 per week.
