Call him :)
Depends on the arrangements you made with him when you and he were making decisions about having a child or about the possibility of having a child, and perhaps on if you can force him to help out.
Is he in any way involved in your child's life? If he is not providing at least financial support, then get the courts involved. In the meantime , call him to give money for his child.
ohh dear<br />
uh oh... another deadbeat dad alert!
Unless he's an MD or pharmacist, no...
