J.S.
Be Straight Forward, its obvious that they DON'T Want the kid or they'd be the ones taking care of him. Get child support on both of them. Go through legal aide and get custody and as far as I know where I live, You already have custody. Your the one that has the kid 24/7. Thats how it worked for us anyhow, when my sister left her 3 older kids with us while her and her bf took off for a few months, which was only suppose to be a month, they got medicade for their kids and food stamps for us to feed them, but NEVER LEFT US WITH NEEDS or MONEY for needs. At the time I was due to have my 3rd child. And very stressed out due to the fact at the time my fiance was in between jobs and we had all these bills to take care of, they never brought clothes suited for the SEASON (WINTER) and none of them had winter coats. So we had to come up with all of that on our own. I went after child support, and it was legal. Just make sure you have his birth certificate, social security card and get them to sign a paper stating that you have their son 24 hours 7days a week. ANd BOOM you got it! Good Luck!!
