I think Ari is trying to lose all of her teeth at once. She lost her right top front tooth on the day before her birthday and then the left top front tooth on the day after her birthday. She looks so cute with her top two teeth missing! She now has 3 more teeth loose. Thus far she has lost 5 teeth!
Above is when she lost her 4th tooth. Below is after she lost the 5th tooth.
I love this picture of Chris and Arianna!
