I have learned that if you don't have a sense of humor while raising kids, you're not going to make it. I have a 2 1/2 yr old and a 2 month old. Of course right now my 2 month old is perfect, but once he reaches his brothers age I'll be pulling my hair out all over again. This is just a funny way to try and not stress the small stuff! I can honestly say my oldest has done plenty for a sign! Mostly for the laughing aspect of it! He peed in his Dads shoe once because Daddy told him no! We wanted to be mad, but how could you? What 2-year-old knows to pee in someone elses shoe!? Of course he had a time out, but a sign would have made it a memory for the scrapbook!
