Toothy Issues

妹妹 has taken up a new habit … brushing her teeth. Each time we are near the washbasin, she will take her toothbrush to brush her teeth. And her has never taken the wrong one before. It’s a good habit as her 4th upper Incisor is coming out. That makes a total of 8 teeth she has. But this morning, I actually saw the tip of an upper Molar. It’s already out? Gosh! But the Canine is not even out yet! Shouldn’t it grow in sequence? I checked her health book and realized the growth of Canine is really after the 1st Molar. Oh … I didn’t know that.
