You’ve started to proclaim, “I did it!” excitedly after doing something yourself, usually putting on an article of clothing or your shoes. Today your dad and I were in the kitchen preparing dinner, and you were entertaining yourself elsewhere. I heard you happily announce, “I did it!” from the other side of the kitchen counter, and upon walking around the counter to discover what you did, saw you seated in your highchair! You’d climbed up the highchair, navigated into the seat (which had the tray on it, making this feat even more impressive), and were happily sitting there. You were very proud of yourself, and got really upset when I explained that in fact, no, we do not climb into our highchair.
