Ideas?

So my boyfriend and I have only been dating a few months. We’ve known each other forever and have no doubts about our relationship. I’m 28 he’s 30 we both have great jobs with benefits. Anyway we accidentally got pregnant and he told me the decision was completely up to me. He really wants a baby but thinks the choice should be mostly mine. I’ve decided to have the baby and want a cute way to tell him. Any ideas?
