My 6-month-old grandson wants to watch the the "VuVu" video while eating. So he starts to scream loudly and crazily, almost like e tantrum, just to watch that while eating. Any suggestions as to how to tackle him?
Don't watch it. Ever. Again. (or at least for a year and a half).
He's too young for the real tantrums, he just wants something and shows it. When he screams, let him. Talk to him in a calm manner, and try to change the subject. A favorite puppet doing something funny, a book, anything that will make him forget about watching the show will be good.
After 3-4 days of consistently not watching while eating he should start acting normally.
Moreover, I suggest that you tell him that the TV is broken (remove batteries from the remote and show him that it isn't working) and not watch it again unless he's asleep or outside. Children shouldn't be watching TV before being 2 years old!
