Yep! I have a very strong willed (read: stubborn, pig headed) DD who will be 1 this week. It was cute for, ummmm, the first five seconds!

She can really bung it on and I've found either distracting her with something else (but not bowing to her requirement!) or simply walking away and leaving her works for us.
I always try distraction first but if I'm frustrated or know I'm going to get cross at her, I just walk away and listen out to make sure she stops.

All fun and games hey??
