Dear mothers... My son watches TV... well, we don't really show it on purpose, but it happens like that because we have a one-bedroom apartment. His bed and sofa are opposite the TV, and the boy watches if the TV is on. I read online that children under 3 years old shouldn't watch... but at home it gets too quiet if you turn it off... Share your experiences with anyone whose child watched and how it affected them?
