velo, you have a beautiful little girl there. I'm certain you are proud of her, and for good reason!
My two little ones are now 3.5 years and 20 months. All I can say to you is this: It just keeps getting better. Sure, there are times when you have to be forceful and tell them to eat their broccoli or else, etc. But as they grow, you can not only watch them develop, you can see the potential of what they are going to be in the future.
It is an awesome thing to observe, and a joy to all parents.
