The Quickest 18 Months

Why is it that when we were younger time went by so slow and now it flies by? I feel like the last year and a half never existed. I can't believe that OK is 18 months old. We went to the doctor today for her well checkup. She weighed 21 lbs 1 oz and is 30.5 inches long. I can't believe my 4 lb baby now weighs five times that. She is amazing. Learning new words everyday. She now mimics everything we do. She is obsessed with The Little Mermaid. She loves playing in her kitchen, singing, dancing, and running from one end of the room to the other. Hopefully we won't have to go back to the doctor until she is two.
