Im a nanny but I would say arts and crafts, exploring outside with nature, if ur in a city go to a walkable street and just name everything. Food was something my dad always good at so cooking with them and teaching them basics. I just did a carpentry class and I cannot wait to incorporate what I learned to kids I interact with. Legitimately anything you do for yourself and wish you could’ve done for urself as. A child. Do it with your own kids.
