Gender Reveal

Thinking of just doing a gender reveal to my husband. I dont really have friends that live here and this is my husbands 4th child, my 1st. I was thinking maybe to make it a little surprise for him and do a gender reveal to him. He works till 2 am, i get home at 3:30 pm so i was thinking maybe do the box with the balloons, and set up a few decorations and let him open it and see what were having. I am too impatient and i thought since this is his 4th, maybe i could do the little surprise for him. Good idea or nah?
