We're getting a lot of help from our parents, there's no way we'd be able to keep him if we weren't.
OH goes to school full time and works part time. We both still live with our parents. I'll be moving into his house once Finn is here, seeing as it's bigger. Hopefully OH's older brother will move out soon and then Finn can have his room as nursery.
Family is buying us all big items (car seat, stroller, crib) and we'll be getting the basics from everyone else at our baby shower as well. We're doing a wishing well, so we should get tons of diapers, wipes, and plain onesies. OH's parents have offered to help pay for things if we ever need it, but we should easily be able to pay for diapers and I plan on mostly making my own wipes (paper towels and a soap mixture suggested by my midwife). It'll be a lot cheaper. I plan on breastfeeding, so we'll save there. We also have a local pregnancy center who will give you diapers, wipes and formula if you need them.
Honestly, you don't need baby food. Buy rice cereal and then make your own mashes. Buy a cheap food processor, boil fruits and vegetables down until they're super soft and then pop them in the processor. Ta-dah, baby food! It's so much cheaper.
ETA: We applied to WIC, but didn't qualify. If you live with parents they take in their income as well as yours. If your baby is going on state insurance once he/she is here though, they'll automatically qualify and you'll be able to get food for them. That's what we're doing.
