They say the first time you do something is the most memorable. The first time being a father? Well, overwhelmingly transcendent. Years from now, ask any dad, and he'll comfortably tell you exactly every single detail. But in case they need a little reminder of how long they've come, get a "My 1st Father's Day" personalized mug from Gossby. It's one of the gifts that make a milestone unforgettable.
