L's first tooth came through on Saturday. It's one of the lower front teeth, and I think that's why her cheeks are bright red at the moment (apparently bright red cheeks can be a symptom of teething.)
N asked DH to take off the training wheels on Saturday and is successfully riding his 2-wheeler! It took him about 10 minutes after the training wheels were removed to get the hang of it. Of course, he's still a bit wobbly, but he's doing great!
