watch tv

Hello mga momsh.. My baby used to watch tv since 4 months, 6 months na xa now. Nanonood talaga and nag rereact din naman sa pinapanood nya tumatawa at sumisigaw pag nagugustuhan nya ung video (cocomelon), but i have just red in the internet na may negative effect daw sa baby ang panood ng tv at early age. What Do you think mga momshie?
