Emily is a little sponge and she loves watching Nolan. So it's so fun when you see her immediately try to do something that Nolan is doing.
Mind you, it's rare that Nolan slows down enough to lay or lounge on the couch like this (which is why it is so picture-worthy). And Emily just needed to give it a try.
Then when he was up and running again she had a try on the pillow.
Then she probably saw a ball and pointed to it. that girl loves her soccer and basket balls!
