did my explanation of meaning answer your posting 'anklebitersmum'??
I don't understand why you say 'nice atitude' to biological parents responsibility (it is supposed to be the law that the parents are responsible).
or why the 'WOW'
I understand your point about costs per child, and why you make it, but I'd have to agree that it seems fair to give a smaller percentage per child after the first one, as subsequent children do cost less. One adult living alone has an exponentially larger outlay than each additional adult joining the house and sharing the costs of heating, lighting, even food shared is cheaper than for one, economies of scale mean that smaller amounts cost more per gram, etc. Please don't think I am attempting to negate the huge costs involved in raising triplets, which is unique in that you do actually need 3 of everything all at the same time and if you had these as a complete surprise, respect at still being legible at the end of the day! ;)
.. and no certainly, life far from ideal, but life should still have ideals, one being that biological parents in the eyes of the law, mean ultimate and primary responsibility for the offspring they produce, always, financially (and emotionally, excluding cases of abuse or neglect).
If you are RP with 3(4) children
NRP started new family and has created another child with new partner
NRP should give you highest priority for responsibility for triplets, but then has his own with another partner that should also trigger a new percentage of its own, but not over and above his outlay for 3.
.. but I might have misunderstood exactly the NRP/RP set up.. i checked it a few times, but its now late again!
