Ay, mahirap talaga ang SSS maternity benefits application, diba? Ang best thing is to make sure your contributions are updated and you've paid at least 3 months of premiums before your expected delivery date, that's usually the main requirement they check. A few of us mums made the mistake of applying too late or with missing documents, so I'd recommend going to your nearest SSS branch personally with your complete ID, maternity certificate from your OB, and birth certificate to avoid delays or rejection.
