This doesn't affect me personally, but I came across this rule on mumsnet and its just been bugging me.
If I coupled up with a man who had DC from a previous relationship, I'd take them into account when working out if we could afford children, just as I'd take my own DC into account. Why should his responsibilities towards his existing DC automatically be reduced after we have another child?
Other countries don't apply this in the same way - in the US it depends on the State and in Canada CM is not reduced unless apply for "undue hardship" (as far as I understand).
Am I missing something?
