Kelsey or Kaley had one of Kinsley's bottles playing with it with their dolls. I was busy doing something and did not realize they had put milk in it and Kinsley found it. The child was so excited. I wish I could have gotten first first reaction to the bottle but atleast I got a little of it. At first, she would take one drink, look at me, smile real big, and say "DOTTLE" "DOTLLE", drink another drink, smile and say "DOTTLE". She was so excited! Bless her little heart. Thankfully, it didn't cause a setback. She is drinking milk from a cup much better now.
