Denise Richards and Brooke Mueller are meeting right now with their business managers and a psychologist for one of the twins to make a case for more child support, because they say the children are at serious risk.

As we reported, Charlie had his monthly support reduced from $55k he paid to both Brooke and Denise. Charlie claimed he could no longer afford that amount, and the judge reduced the support payments to $10k each.

Sources connected with Brooke and Denise tell us, they cannot afford to cover basic bills. We're told one child is receiving significant psychological help and there are other needs as well among the 4 kids.

We're told insurance is not covering even basic bills, and neither Denise nor Brooke can cut it.
