Child Support ??

How do you go about dropping child support ? Me and my daughter Father struggled for a long time to coparent it was always a huge fight/argument anytime I asked for help financially with things our daughter needed it got to the point we didn’t even speak to each other for 5 months he made no effort to help . I took out child support during that time finally he reached out to me apologizing willing to do what he needed to coparent , he pays the child support but also helps me now paying half of the daycare bill and buying all of her clothes and shoes when needed as well as keeping her every other weekend when he has off due to his job. I feel like we have came a long way from where we used to be and I appreciate his effort and finally stepping up . He has not asked me to drop child support but I feel like he is doing everything that I asked plus more to coparent I feel it’s only right that I drop the child support but I have no idea where to even start with that .
