Linden has had some trouble for a few weeks now using her sippy cup so I tried the bottle. She hasn't had a bottle since she's been 5 weeks old so I wasn't sure how she would do. She did great! Sucked the whole bottle of Pediasure down! After about a week of sucking on the bottle, she can use the sippy cup. Yay! Here are two pictures of her last night watching Baby Einstein and having a bottle. I give her the bottle a little more often because it's easier to hold as she has no fingers on her left hand.
