I got the idea that she saw how stressed her mom was and thought it would be nice to make tea but it didn't feel convincing. Also, it was a bit of a stretch to think that all of a sudden the 2 year old thought that instead of making fake tea she would make real tea. Maybe if you had opened on the mother being stressed and the daughter decided to make tea to help out it would have flowed better.
Besides that I caught myself saying "aw that's cute" or "hey...my daughters have done that!" or "OH NO not sand for sugar!".
Overall very well done and you sucked me in pretty good.
