How did you tell your husband?

This was our 10th month trying and finally did it. I had always planned I would make his coffee in a mug that says Dad and see how long it takes for him to catch on but unfortunately he works night shift and I work during the day so I don’t see him in the mornings. I had to come up with a quick plan and came up with this.

He came in at 3 in the morning and I heard him look at it forever! I love looking at how other people announced. How did you do it?
