The funny part is that my daughter gave Mickey a hug and still wouldn't sit on Santa's lap lol
My 11 month old had no clue who Santa was, just some strange guy to her. But it struck me as odd since she went to my relatives she didn't know with no issues. She actually goes to most strangers (to her) with no issues. But Santa, no way. Disney photographers are AMAZING though and managed to get some non-crying somewhat OK pictures with her on his lap. I was amazed that they caught her right at those perfect times.
Oh yeah... back to topic.
My daughter will be brave at the entrance, but HTF is right, most kids will chicken out at the entrance or in the line. I just have a head strong child that is way too stubborn when she convinces herself she can do something.
