What To Do???!!!

So I always sit around and think about the future. I think how I want to continue to be a SAHM. It makes me feel important. But Hubby says that we shouldn't have anymore kids because my last labor did not go so smooth and he doesn't want to lose me. Plus, he says that he wants us to still be young enough to have together time after Samantha gets old enough to move out and be on her own. We have talked about adoption, but it costs so much. So we thought about fostering kids, but I would get so attached. PLUS, there is Samantha to think about. Would she even feel comfortable having other kids in our home-kids that would take much of my attention? So many choices...maybe I should just continue to work with kids-continue volunteer at the daycare, keep teaching Sunday school, become a pediatric OT instead of geriatric...I feel like I have to decide soon. I am only 18 years old, but I feel like there is so little time. 8(
