Babies

Ok, so me and my husband just got married on dec. 4th. And I been thinking lately that I want to start to try to have a baby, but idk if it's the right time because we are both about to start new jobs and he had a little girl 4 years ago so we have her and we live with his parents right now. 
1. Should we start trying.
2. How do I tell him, I want to start trying.
