Guess Who

Here's a little game to test how well you know my sister and me.  Mommy saved one of Big Sis Ava's outfits and dressed me up in it as well.  Fortunately, yellow duckies are gender-neutral.  Mommy even got the same white blankie and took my picture at almost the same age (I am 6 weeks in mine and Ava is 6 weeks, 2 days).  So, can you tell who is who?  The answer is at the bottom.

The top picture is of Ava and the bottom one is of me.  Did you guess correctly?
