Sippy Cup & Hayes' Way of Saying "No Mommy!"

Hayes is really trying to figure out this sippy cup. He can't decide which side he likes to drink out of better. Also, he has a new thing he does when he does not want to eat something I am trying to feed him. He sucks in his lower lip and clamps his mouth shut. Then he will look in every direction except where I am. LOL! Stubborn Stubborn!
