Relationship/$$ advice

My husband and I are 11 weeks pregnant and money is really tight. We have an option to move into a family home rent free. I'm concerned about getting a nursing degree incase anything every happens to him I want to have a secure career. And we can't afford for me to go to school if we stay in the house we live in now. Well barely be able to afford diapers. He wants to stay in our home and try to make ends meet. I want to move into the family home so we don't have to struggle. Any advice?
