Best way to convince your husband to have another baby

Shelby
So I am having major baby fever. My husband is set with our 2 kids. He says he doesn't want anymore but he talks about names if we have another and how much he misses our daughter being tiny (she's 13 months and he cried two days ago because she's not an infant). I can tell he is starting to want another. How do I help him get on board. I just want one more! Haha HELP!
