If you spent any time with my dad, you would quickly find that he loved babies and kids. It didn't matter if he knew them or not. He would do anything to protect them and bring a smile to their face, especially if they were his grandbabies. I will forever remember the calls I would get. "Hey Baby Doll! I want to help the kids. Take my card info and put it where they need it most."
So in lieu of flowers, dad would want his memory to touch kids around the world.
