Ah, the pleasures of a new talker! Gavin does not say the bane of all mothers, NO! Instead he will look at you really intently and emphatically state STOP! He is very good at expressing the "sto" but hasn't learned how to put on the final "p" it is so cute that I have to giggle each time he says it. I'm sure as he continues I will stop thinking how adorable it is!
