AIBU at the level of child support payments

[craxmum]

Ex is on £120K + bonus. Calculated child maintenance for 2 children (2 and 4) is £198 per week, and he will not participate financially in any other way - this contribution covers only a third of childcare costs, nevermind anything else.
AIBU to think that is ridiculously low?

I don't have access to public funds (free hours or subsidised childcare).

The CMS take into account his newer children and reduce payments to yours accordingly. Unfair but true.

You sound we'll rid if him op. Charming to uproot you and then drop you!
