I second the shirt. I'm thinking about getting one for father's day since I'm due around then
There's customizable Keychains or placards the size of a credit card that you put the ultrasound picture on and it says, "now you can hold me too, Daddy"
Seraphine do these baby wearing tshirts for men, could also look for picture frames to frame ultrasound scan? Or get the scan made into something small he can keep on him or at work?
