Christmas with a toddler was a really neat experience. She saw the presents under the tree, but didn't really understand them. She picked up one or two of them, but when asked to put them down, she immediately did.
When it was gift opening time, we gave her a present and helped her unwrap it. She was SO thrilled to get each gift that the new item became her whole world. She played and played, and didn't want to be interrupted with another box to unwrap. By the end of our time, we were opening presents for her.
