Early Fathers Day Gift for Delivery Room

So, I have a 6 year old son whom my husband LOVES AND ADORES!  He has cared for him since he was 3... Now, my husband and I are expecting twins in the Fall and I couldn't think of a better gift for him because he has always celebrated Fathers Day (as my son sees him and respects him as daddy...EVEN THOUGH he has a great relationship with his other dad).  Long story short, this is TECHNICALLY my husbands FIRST "real" Fathers Day, and this is one of the early presents we got him to wear on our delivery date.  I want him to feel. special.  What do you think? Scrubs that say "daddy" on the front and "I'm your daddy" on the back. A coffee mug (to keep him awake just in case), pens to take notes and sunglasses for the effect...
