DH and I share a document on Google Drive called, "LO's Lexicon" and we add new words and phrases she learns to it. I added a couple of words last night that we had been meaning to add and thought damn, we should have added the age she was in months. We are going to put the list in her 2 year book.

Do you keep a list? Or are DH and I the only dweebs who do this?
