I think I forgot to show this earlier. This is a plastic box filled with aquarium gravel that I sometimes bring out for the three-year-old. She likes to feel as if she is having school alongside her older siblings but she can’t sit still long enough when we are having a little one-on-one time. We’ve used ocean animals, cars, and plastic cups so far and she’s very focused and quiet when she plays with it.
Sometimes, the older kids tell me that she needs “help” and that she’s “not doing it right” and that’s why you see the extra hands, lol.
