I don't understand why I need proof of residence and proof of income when I already have wic and my husband and I still live in base housing like we did when I got it. that just fucking ruins everything bc sullivan isn't doing good with this formula and I was hoping it would just have to last us through the night until I get more checks tomorrow and now I'm just gonna have to pick another formula before we actually start getting whatever wic is gonna give him and I'm just so frustrated.
