I have photos of our daughter being held by several characters -- Alice, Cinderella, Belle, and Mary Poppins -- that were taken at CRT in late 2004 on our first trip to WDW as a family of 3.
At the time, our daughter was 23 months old, and looked just like a real life version of Boo from Monsters Inc. She adored the characters and parades, and we had gone to a parade earlier in the day where she had been waving and blowing kisses at all the princesses. Alice had skipped up to her (Alice wasn't on a float) and made a big fuss over her. Then later that day, Alice came up to us in a very long line at CRT to take our photo with the Fairy Godmother and made a big fuss over our daughter again, telling her she remembered her from the parade earlier that day. Our daughter reached out to her to give her a hug, and when Alice hugged her back, our daughter just kind of melted into her arms, lol. Alice was so sweet and was so clearly touched by this, and stood there just holding her and rocking her back and forth and saying how sweet she was. She asked if she could introduce our daughter to the other princesses who were in the castle that day, and within a minute or so the other 3 were over with us taking turns holding her and hugging her. This went on for about 10 minutes or so while we stood in line, and we were shocked by how much time they spent with her!
I honestly didn't know this was against the rules (though in hindsight I can certainly understand why). My husband took a lot of photos and even shot video of it because we were just so surprised by how much attention she got from them, and how much she ate it up at that age! Honestly it was the cutest thing ever, and a wonderful memory that my husband and I both cherish.

I couldn't find the photo of her being held by Mary just now, but here she is being held by the other 3, with her face slightly blurred for privacy reasons.
