Teacher/graduation/prego announcment

Hey ladies.. I'll be 9 weeks when j graduate with my early childhood teaching degree. We plan to announce at my grad party.. What could be a cute "saying" to reveal our news on a graduation cake? I was thinking.. It could say something like, " from cap and gown to____"  and end it with something about a baby that rhymes with gown?! Or maybe have this onesie and have my hubby act like he is going to give me a gift and pull that onesie out..😘  can ️yal help me come up with sayings that are cute and "teachery" that have to do with a baby? HELP PLEASE 🙏😍
