The What to Expect in the Toddler Years Book says that soon Sadie should be able to remove one article of clothing. We actually already have that one covered. She is in the 25% of thirteen month olds that can take of her pants. Twice I've come into the room after leaving for just a moment to find her pantless in her playpen. I'm not sure how she does it, because I've never actually seen her in action. I just know that one moment she's wearing pants and the next she's not.
She also said what sounded like "I love you" today. When it was repeated back to her she laughed hysterically. I'm taking that as confirmation that that was actually what she meant to say (wishful mom thinking?).
And we've started a weekly tradition. We discovered today that our library has a board book section. So far Sadie is a bit wary of the books that we checked out (they are clearly not her books, i.e. the books she has memorized) but I think they'll grow on her. Just in time to go back to the library.
