Drinking From A Straw

About a month ago, I finally got Shelby to begin drinking from a sippy cup. The only problem was that she refused to hold it. So Jeremy and I have been holding her and the cup. So I started just putting it on the floor in front of her to see what she would do. And she did absolutely nothing. She would just stare at the cup and then smile at us. But the other day she found one of Gabe's cups with the straw. She started chewing on it and then all of a sudden, we heard her sucking really hard on the straw. She had drank all the juice out of the cup on her own. Jeremy and I were both clapping and cheering for her and of course, she gave us that cute toothy grin. Now Shelby only drinks out of the straw cups and she does it all by herself.
