I tried to understand your facts but sorry could not understand them the way you stated them. Does your wife have green card or conditional green card?

Your wife could apply for you I130 & 485 -- your baby is good evidence of a bona fide marriage. However, her prior marriage would come up and there will be questions. Advisable to get a lawyer to assist.
