Can my baby mama not let me see my kids because I have not paid child support last month. I'm been looking for a job.,

Well, who knows who she actually spoke to (if anyone) and whatever that person might have said, but the short version is "no."  While there are old cases indicating otherwise, modern law is that custody and visitation are separate -- a failure of one does not affect the other, certainly not automatically, and perhaps not at all.  Her remedy is to file a motion to reduce arrears to judgment -- and yours is to file a motion seeking to enforce visitation.  Each of you could of course file a countermotion to any request made by the other, but they are not directly dependent on one another, and each will be treated separately.  See: http://www.willicklawgroup.com/child-support/ http://www.willicklawgroup.com/child-custody-and-visitation/
