If Charlotte watches Mister Rogers, you might see if they have corresponding activities to go with the shows online. They used to sell a book of activities that coordinated with the shows, but I think they do that online now. I used to have the book, and it seemed geared for daycares who need planned learning activities, so it might have just enough stucture for you right now.
Here's the Mister Rogers website:
