Should Reverse Out Of That Line Of Conversation

(I am five months pregnant with our first child. My husband is lying in bed watching me get ready, as I work on Saturdays and he does not.)

Husband: “Aww, look at that little bump. That’s our baby!”

Me: “Yep, you can really see it’s there now.”

Husband: “Won’t be long before we have to put reversing beepers on you.”
