@Jellybean : Naptime was a must do with my young ones, if none then it messed up the rest of the day. Although when I hear/see kids crying at the grocery store, I know.
I had one. It was also not a good idea to wake her up. Even her older sibs would not wake her. IF she managed to get any Pepsie, it was not a good time at our house. Needless to say, we kept her out of Burger King.
