My little boy is 16 months old and can say, "A,B,C,D"! We sing the alphabet alot at our house. He has also recenly become a huge fan of climbing in higher more dangrous places than ever before. It kindda scares the crap out of you when you look over and your toddler has climbed about 5 feet off the floor onto some piece of furniture. (Like a computer desk!) But I guess that's life with our JD. :)
