No, you're attempting to manipulate what I said to suit your own agenda...but it's not going to work.
£2,400 per year would not cover half of a child's basic needs (housing, water, warmth, clothes, food) , that's what I have said and that's what I stand by. The OP was clear he doesn't have any overnights and that's what the PP was basing her theory on, so that's where the figure came from, are you keeping up?
If the children aren't staying with NRP overnight then they do not require a bedroom, therefore you can have a smaller house and lower bills, whereas the RP has to have bedrooms, beds, bedding, the heating on in the winter, all of the clothes they wear etc...do you see the difference, or are you going to close your eyes put your fingers in your ears and cry "lalala" because the facts don't suit your narrative?
You rushing on here to shout about how much your husband pays (fantastic for his children, they are very privileged - you're clearly bitter about the fact he's ensuring they're finically stable though - says a lot about you as a person) and complain that it's too much and they can't possibly need it...has zero relevance to the point the PP and I were debating...which is £2,400 a year is not enough to cover half of a child's needs if you don't do overnights.
Do you now understand that the amount of overnights your DH does or how much he pays will never be relevant to that point - because the basis of the debate was zero overnights and a £2,400 yearly total?
Anyone could come on here and say "well I do x overnights and pay y amount so it's not fair" and that would also be irrelevant!!
And as a side note, if your DH is earning enough that CMS have said he has to pay £500 per month then he's on a pretty good salary - and only paying £6,000 per year for 3 children that he has for less than 1/3 of the year. According to FC and CMS if they are only staying over 100 nights per year they are not deemed as requiring a bedroom - a sofa bed would suffice, you should absolutely be providing clothes, haircuts and childcare if you need it - any clubs, sports & equipment, tv subs, larger car and lessons are a choice, CMS aren't saying he has to do those things, he's choosing to - so you don't get to offset housing costs and choices your making to claim you're paying to much.
Here's some perspective for you, seeing as you seem to think you're paying too much...
The average cost of raising a child in the U.K. is £14,000 per child, per year, that's a base rate...so your £2,000 per year, per child doesn't even touch the sides...and RP also has to take every school sick day if you only have them wknds and hols, so don't forget that little gem!
Honestly do not understand step parents who begrudge their DSC a decent upbringing - my DSS gets everything he needs in our home and we still pay his BM CMS, despite the fact he's with us 3 nights per week every week. I cannot imagine sitting down and writing out all the things we do for him and parading it around like we're heroes for doing the same for him as we do for the others, literally just the bare basics of being good parents...it's so distasteful.
If the situation played out as you claim it did (seen that excuse too many times on mumsnet for it to be the truth every time) then your DH and yourself could have moved - seeing as the money bothers you oh so much, it's not like he hasn't had several years to find a suitable job and home - but you don't want to do that, so don't then moan about the money...because there are always options for people who genuinely want to be with their children...the excuses are often easier though 🤷🏻♀️
