i think that's a 15 month milestone

We were playing Maltese Catch (wherein a stuffed animal Maltese puppy is tossed back and forth), and she threw it to me. Her unsteady 4 year old aim resulted in baby sister getting socked in the face with the dog.

There was that shocked pause where you wait to hear if a baby is going to freak out... it was interrupted when Caroline cheerfully directed, "You gotta think fast, sista!"
