OP asked about 2yos. When my mother was 2yo, during WWII, her 20yo sister was at home to help run the family, and the sisters were close then although not again until adulthood.
I was minded by nannies so presumably, as paid staff, they didn't put the telly on too much. Also we lived on the beach in a sunny benign climate, not like rainy cold Britain.
When we lived in a Bangladeshi neighbourhood 10 years ago, I sometimes noticed 2yos out playing for spells, minded by cousins or older siblings (only, no adults). So there you go, traditional child-rearing practices if only you know where to look. Also, at home there were so many other children about to play with, typically, and telly only available in a non-household language, that I doubt those children watched much TV, either. Probably different now, I bet there's a satellite Bengali channel now with some children's options, even.
