Wic question

Hello. Im a ftm mom and I am going to apply for wic. I'm 18 and live all by myself with my 2 month old son. I don't have any form of income because I just moved into a house owned by my family. I have money in the bank to pay the utilities until I get a job I don't have to pay rent. When I apply for wic they want proof of income. What do I do since I don't have any form of income?
