My understanding is that if your wife works and takes FMLA leave than you would be ineligible. One of you can take it, but not both. Just be aware that FMLA leave is, by default, unpaid leave unless your company/employer has specifically adopted a policy for paid leave. Also, if you or your wife's company has fewer than 50 employees the company is exempt from offering FMLA leave. Google will be your friend on this but as a start you could do some reading here.
