I made Jaxon a shirt that says Big, Owen a shirt that says medium and Rohn a onesie that says Small. Then I printed off some Dot to Dots and Mazes and a match game and included a new car and of course some snacks (a juice box and gummie bears) my boys loved coming to the hospital and getting the surprises! Plus it helped to keep them occupied while I was waiting to be discharged.
Here is a shot of my three boys in their shirts. It cracks me up!
