Helppppp please - moving out

Sorry if this is long. I'm having some serious anxiety right now! My husband and I had our first young and are pregnant(12 weeks) with our second less than 2 years later. We've been living with my in laws for relatively cheap. We have a car payment and ins on 2. We found a place for ourselves and although it's a great deal I still don't know how we are going to afford it. Right now he is working full time and I'll be finished with my degree next month so only one income at the moment. Its putting a lot of pressure on me to get a job asap. We will be moving in the next month if everything goes as planned. This will be the first time we've lived out on our own. We have a lot of house supplies(appliances, furniture, bedding etc) from our wedding gifts but need basic stuff plus idk what else since his parents buy normal housing basic. Sorry if I sound dumb but what stuff do you usually buy for a house(like tp, cleaning supplies, etc), maybe some housing costs I'm not thinking of and any tips on saving money?
