Congrats!!
This was a surprise pregnancy for us, so I wanted to do something fun. I happened to be working from home the day I tested, so I ran out on my "lunch hour" and got an "I'm an awesome Big Brother!" shirt for DS. DH and I had plans for a dinner date that night, so I gave him the shirt then (DS was with my XH for his weekend) and said "Check out the shirt I got for DS. Think he'll like it"? He thought I got it as a joke until I showed him the pic on my phone of 4 positive HPTs. :)
