I baby sat DGS (4 and 6) a few weeks ago - we were staying for a few days and I brought a bunch of little surprises that I brought out one at a time. So for the last night, when the parents were out and we were babysitting, I had a package of balloons. I blew them up and let them fly around the room. Well, let me tell you - two hours of non-stop fun!! And the last one was just as hilarious as the first one. Not to mention making funny noises letting air out. I wish everyone could enjoy life the way little kids do.
