For my 1st I just told him. With my second I made him a onesie that said Proof my dad does more than play video games. Then put the controller on the butt. I lost that baby at 12 weeks. So with my last baby I was nervous and just told him.

... first time I put the test in his hand second he knew I was pregnant before I told him

On his birthday I bought him a basketball jersey so I bought the matching little newborn jersey set in the box and taped the ultrasound to the back.
