How do I suppress my urge to have a baby?

Sit down and talk with him, ask him when does he think he will be ready for the responsibility. Truly, because a child is a huge responsibility that not everyone wants immediately. You much rather have him ready than to have him hate the fact that it happened so soon, and just neglect basic responsibilities. That’s unhealthy for both of you. If he isn’t ready, you’ll have to wait until he’s sure because you can pick your husband, but your child can’t pick a father, so make sure it’s a good one.
