When my in-laws are with my 7 month old son, they ALWAYS have the TV on which completely stresses me out. They do play with him (usually on their laps), but it is always on. (Note: Nothing violent is shown at that time.) I have mentioned multiple times that I do not want him watching TV so I never have it on; and yet they don't catch on. They probably visit about once a month and stay for 2 days at a time. Is this doing harm to our baby?
