I want to have a baby but I'm not sure how to bring it up to my boyfriend or how he will react. We aren't married or engaged yet, but  we've been together for 4 years and he always tells me he wants to have children with me and he'd like to be a father by the time he's 25 at the latest (which is about a year and a half away) I've made like little hints about it but he doesn't really pick up on them. Or if he does he doesn't say anything about it. What should I tell him? How should I tell him? Should I be more up front about it? or should I wait?
