Hello and

hoody,
It sounds like you have two separate issues to look at here.
First, your legal rights and obligations. You may be required to support the baby and her. You probably have some legal right to contact with your son. Are you married? Divorced?
Second, what do you WANT both with her and with your son?
Do you want full or partial custody?
Do you want to reconcile with her?
And what is your relationship with her mother like?
Whatever your answers are... .we can help you here with support and with tools to make things go more smoothly.
Hang in there!
