Then Mom can (and should) go to jail right along with you.
I'm going to give you a clue here. With the possible exception of john, who doesn't know beans about the law, you're not going to find anyone here supporting your position. Yes, right now you have a choice; you can "give the child your name" (translation - make sure everyone in the world knows that I have a functional reproductive system and am too horny to keep it leased even if it means committing a felony) and potentially go to big-boy prison, or you can leave well enough alone and hope that you can skate along under the radar until the SOL runs out.
And if Mom knew and approved of what was happening, there are charges that can be filed against her as well.
