Wanting to try for #2

Athena
Hi all! I am 32 yo full time nursing student at the end of my junior year. I am hoping to try for #2 this fall, but my husband isn't convinced. We have a 7 yo now and he thinks the kids will be too far apart and I am getting too old (higher risk) for us to try. I feel like I lost my chances of a second child with going back to school. Although when we discussed it when I went back to school he was up in the air about another one, but lately it seems he is more against it than for it. Not sure how to convince him that we will have a healthy baby and I am not that old yet. Any suggestions?
