if the mother isnt paying child support and isnt getting her son when we ask on her weekend are we able to start recieveing child support even when

If the Mother is not exercising timesharing, and the other parent is the one who is primary taking care of the child, than that parent should petition for child support. I suggest you contact your local child support office and they can help you to initiate a child support case.  Best of Luck, Helena Y. Farber, Esq. Farber Law, P.A. P: 305-520-9205 www.farberlawpa.com
