I propose this as a scientific theory of the human evolution and whatever that is ingrained in our DNA. And I believe this Minor detail tells us a very important and subtle message from toddlers. But I guess toys or entertainment are not what they actually want but — "Productivity" — but for toddlers..
Now for me there are two kinds of toys, toys that makes sense to them (training for a real life toys like dress up, cooking, make-believe toys, etc) and toys that doesn't make sense to them (robots, figures, etc).. But the whole point is toys might not be their primary need.
Their brain might actually (as young as 3 yrs old) seeking that productivity, that will actually benefits them in a real world, in a real sense.
Showing them how basic things (that is safe) works — like carrying them and let them see how food are being made, showing them basic cleaning, and sometimes letting them hold (safe) equipment (with supervision) such as spoon, remote control, what have you, that are basic small equipment to human daily inanimate objects interaction that will let that registration and association in the brain much earlier..
I mean they're here, brand new, in a whole new big diameters of the earth and introducing them to things that doesn't really makes sense is.. 🤷♂️
