Should we Teach LLMs Baby, Toddler, Child Talk [D][R][P]

I found an interesting problem recently with a prototype I am working on I will likely post more on in the future. Suffice to say the problem is using an LLM to simulate a child. The goal being to create a simulation tool that lets caregivers interact through specific scenarios to practice handling children of different ages in different situations. I suspect you can see some of the grey area ahead already. That will be my next post.

For this post I want to focus on the responses I am getting from the LLM. Essentially all the LLMs are too freaking helpful. They have been trained on adult data from the internet and books and they have been fine tuned to be helpful. For anyone who has experience with toddlers and teenagers, we'll just say this is not a common outcome, especially in stressful scenarios where a tool like this might be most helpful for training. (Yes the grey area post is coming... not here not now please.) The responses are also too developed in their language and thinking. Some of this can be managed with harnesses and hard coding but it always still slips its leash and goes back to Mr. Happy to help bot.

This also got me thinking farther of should we be trying to include baby, toddler, child speech into training datasets (Open AI dont be evil please... 😮‍💨️), its actually how we all learn speech and a lot of our world model is from this childhood interaction that largely goes unrecorded as text. This language is actually quite rich in discovery language and asking rich questions to fill in gaps in their understandings. When you sit down and actually listen to how kids interact they are asking really really precise questions based on their very incomplete world models about gaps in their own knowledge showing really cool self assessment capability. We also see rapid jumps in behavioral changes associated with these linguistic advances such as the separation of imagination and reality (hallucination), so important behavior may also be somehow encapsulated in this childhood language.

There is also a lot of neural annealing development stuff going on alongside the language progression but LLMs use text at the moment.

TLDR:
Should we include childhood language in model training data? Is there important language and logic structure in that language and interaction?
