Question about WIC and income requirements?

In my last month of pregnancy, I signed up for WIC. At the appointment, I told them my fiance and I lived together but we're not married and they didn't ask for any information about his income, just based my qualification on my income alone. When my daughter was born I called to get her added on, and they made another appointment for me to come in. They told me I only needed to bring my daughter, as well as her crib card from the hospital. My daughter was 6 days old the day of the appointment and I wasn't comfortable taking her out on my own yet so my fiance came with me. When we got there, they asked for proof of residence and income [which I'd already provided at the first appointment and had not brought with me] as well as proof of income for my fiance [also something we had not brought.] I asked why they were including his income if we're not married and they said they have to because we live together. They knew we lived together the first time I went and his information wasn't needed then, so why do they need it now? With his income, we're just over the income limit [literally not even $100 over.] I have another appointment at the end of next month and they've told me to bring proof of residence and income [AGAIN!] as well as his income information. My question is, since we aren't married yet are they able to include his income?
