We've been pretty lucky with that. Even the first day we let them out of the box when they brought them home, it was already up. They were curious about the tree, and maybe batted a few low hanging ornaments, but quickly just let it be. Now Carl loves to lay under it and watch the birds out back. Lenny doesn't seem to care one way or the other. He just sits in his chair and takes it all in.
