For a few months now, whenever Lulu poops in her diaper, she announces it and immediately requests a diaper change....so, last weekend, we were out to lunch with the Graham family. I was sitting next to Lulu who was in a high chair. We were in the middle of conversation when Lulu loudly (and proudly) announces to our table, "UCKKKKKKKKKKKK", quickly followed by "DADA!!!!!!". I explained to Penny and Dave that I have trained Lulu to call for Dada when he is around and she has a poopy diaper. Thank you, Lulu!
