My parents had the same issues too, which became one of the reasons why I sent my son to childcare when he was 2 years old - we delayed it for a bit but he just wasn't making good use of his time at home (my parents gave him a lot of screen time on top of that just so he wouldn't bother them from their own TV show/mobile games).
And yes, there are many "horror" stories of putting children into childcare - but there are also many good ones too! My son is in childcare for 3 months and he has learnt to be more sociable, independent and even helped with his speech delay :) He loves school so much that there was a period of time he woke up in the middle of the night fussing to go to school!
