The advent calender has become quite the fixture in the O Family household. Boy O enjoyed it solo his first Christmas with us and last year Baby O was able to join in the fun. Sometimes it's candy, sometimes a small toy, but I saved the miniature whoopee cushions for the 17th which coincided with a special visitor. Such fun.
Their Grandpa aka 'Chief' also brought a larger version and we had fun with them for a couple of days until they kicked the bucket from too much use. Nothing better than children erupting in giggles before you even have a chance to sit down. We also enjoyed subjecting Newbie O to the festivities. I think she got a kick out of it as well.
