P.,hi. I remember what a wonderful and magical time it was when my daughter was 2 years old. How fortunate you are to have such a lively toddler. I would be greatly concerned if your 2 year old was anything but spirited and energetic.
Having a 2 year old requires your full attention and participation. This is a vital age of exploration and understanding. To attempt to "calm her down" would be in comparison to denying her the freedom to blossom. Her spirit is vulnerable and it is up to you not to alter it.
At 2 years old, we enjoyed making music with an array of instruments and fun keyboards surrounding us. We also loved to paint and bake together. Nature hikes at this age are incredible experiences. The more interaction you have with your 2 year old, particpating in constructive activities, the more you will see her contentment. She might actually sit for a few hours to watch a movie every once in a while!!
The holiday season approaching is a perfect time to focus on activities with your 2 year old. I wish you the best of luck!! And ENJOY her!! She'll be off to college before you know it!!
