Let's see #1 is the expert roller these days. She has such fun with it. Number 2 does the stairs well after the big first one. The first born is curious and loves to explore. The third one looks and creates fun. they don't play bite with each other till the other one lets out a sound. They don't seem to be all that rough with each other.
Here is the gallery today. I hope I clicked some good photos for you.
I did manage to get some fun videos and one is doing stairs. Be sure to check them out.
