I understand what you are saying so I will address the core of your question instead of just giving you things a child can do.
An LLM right now is still just a facsimile of one of human's cognition. Arguably, without the other senses, it can't experience or understand things the same way we can. This leads to the AI unable to form a comparable sentience to a child, at least, not in the same way and not in a way that would be recognized by most people.
Someone already gave you the sense of time as an example. These senses are things we were born with and critical to our perception of the surroundings. Until the AI is trained on at least the majority of these senses, a child will always have something they can do that the AI can't.
