I have officially moved her into 24 month clothes. They are a little big and that is great because I have a lot of 24 month winter (Christmas!) clothes for her so she needs to be in this size for a long time! But the 18 month ones were really too small.
We've been working on keeping bows in her hair. Some days are better than others, but we are starting to figure out which types of hair things she'll tend to leave alone and which ones she just wants to take out and play with.
