Babies and Boyfriend??

So my boyfriend has always said he didn’t want kids. I knew that, I love him and it’s really not a deal breaker for me. If I have kids great, if I don’t that’s okay too. Whatever god has planned for me is okay. The longer we have been together though (3 years) he has been a little more open which is cool because I wouldn’t mind having a few mini me’s running around lol. We have always said if we have kids though we have to try for a girl for his mom because she had three boys! Lol she wants a granddaughter. Anywho, the other day he said that when we have kids I would have to be a SAHM because of how he works, he is a fireman and EMT both jobs he works 24-48. And only has the third day off. That shocked me because a few days prior he told me that he didn’t want kids any time soon. Then this morning we were laying in bed and he put his hand on my belly and said “I’m going to put a baby in there.” I said not any time soon because we just need more time to be prepared. I’ve never seen myself as a SAHM, but as we talked about it, unless we paid for daycare I would have too until the child went to school. How would you take all of this? I’m happy but so confused lol
