moving in with my parents ?? should we ?

My bf and i are 21. i an currently 31 weeks pregnant. When we found out that i was pregnant we decided to get our own apartment, because well it was time to be adults and take responsibility. I have my own car. He did too, but sadly his car broke down and we were not able to fix it. So i always take him to work. He’s the only one working since im really close to my due date. We have been living check by check sadly. So he’s always stressed out that he cant save up for a car and blah blah. My parents have told us to go live with them and just pay for our room and thats it, so we can save up some money for his car and the baby. My bf told me last night that we should, but i dont know if its a good idea... what are your opinions...? Should we live with them for a while until we can get ourselves back in our feet? because if we keep living like this. Check by check we will never be able to move forward. opinions?
