3 years, 4 months.
After watching you brother accidentally yet successfully make creepy tapeworms to fight each other, you decided you wanted to join in on the fun.
You asked me for toothpicks like I gave your brother. I let you have two, but I decided that orange straws to match your orange Play-Doh might be more interesting to you. A few minutes later, I threw in a liquid medicine dispenser as well as a tongue depressor.
For a 3 year-old girl, this perfectly challenged you for an hour. You had so much fun figuring out the many ways you could incorporate the Play-Doh accordingly.
I will have to remember this simply yet engaging activity for next weekend too!
