Child support and access are seperate issues - two wrongs dont make a right, he isnt paying to see his child but to help the primary carer raise them

Also irrelevant to bring up their financial circumstances which you can report to child support if you feel it is inaccurate. I mean really, the paying parent gets to pay a capped amount (sometimes not even that )then wash their hands. The primary carer doesnt reach their allotted cntribution then say oh well, thats all you get kid good luck not starving.

There is really no excuse to skip out on the responsibilty. You dont control the other parent but you are in charge of your own actions - why make your ability to do the right thing dependant on another person? If he wants access he should take it up in court not protest at his childs expense.
