We are doing a science experiment. Ayden lost his first tooth yesterday! He is super cute with his little gap. His twin sister Ksthryne has been asking me to check her teeth about every hour (she is a bit jealous I think). So I explained that when they were babies, her first tooth came in three weeks after Ayden's first. Which gave me the idea.
I introduced the hypothesis that her first loose tooth will be in three weeks.
For the next three weeks we will check her teeth every morning and evening. The chart will have an X for no, a check for loose, and the image of a tooth for the day she looses it. Then we will compare to when she got her first tooth.
If it happens after three weeks we will continue the chart with a weekly update. The picture is my rough draft. I will do a more fancy version on poster later this week lol.
They will have small copies for their kindergarten science journals.
