So . . .
We went to a salon. Am I a total pushover as a mom? Maybe. But it was a spectacular time; Katie felt like a princess, and I felt like the best mom ever as I watched her smile and giggle expectantly. She told the stylist she wanted it shorter and curly (like it isn't curly already!). So, the stylist trimmed it, then curled it in ringlets with a curling iron. While she was busy with that, I painted pink sparkles on her nails, and she got a swipe of my lip gloss. What more could a two-year-old beauty queen want?!
Here's a shot of the finished product (she really was happier than this, it's just hard to get a two-year-old to stand still for pictures):
