I have a few great memories. DD1 was 3 1/2 on her first visit, and was obsessed with all things Minnie. Unfortunately, I was not a very good mom, and I had not done a good job in preparing her that the characters are huge. As a result, I have a great picture of DH holding a shreiking DD near Minnie. She did warm up to the characters by the end of the trip, but her next visit (16 months later) was much better!!
On that first visit DD2 was 6 months, and she was 22 months on our second family visit. After the first time, I got much smarter. First off, I found the DIS! I also ordered the planning DVD which we watched frequently before going on the trip. DD1 was now 4 1/2 (almost 5). She had no problems with characters at all. I was prepared for DD2 to be wary, but not really expecting it since DD2 is our adventurous one.
Our first night we has a PS for Chef Mickey's. I did this on purpose to try to guage the girls' reactions to the characters. Donald wa greeting people that evening, and DD2 just about kneecapped him running up to him to hug him. And when he bent down to hug her, she kissed him right on the beak! DD1 hung back a little, but did have some fun with Donald too. Later in that trip, DH and DD1 were on Splash, and I was in the play area with DD2 (she wasn't tall enough yet!). Next thing I knw, she takes off towards the exit for Splash (she is my adventurous one). By the time I catch her, I see what caught her attention: Brer Bear. He was somewhat hidden, so no one else was around. DD2 ran right up to him and just craned her neck to see him. Fortunately his handler had seen DD2, so he said something to Brer Bear who then proceeded to play with DD2 for about 5 minutes. It was very cute!
