My baby is picking up the language from TV serials. I really don’t want to stop watching, what to do?

no, you don't have to stop watching them, but why don't you watch them at a time when your baby is sleeping or not around? you can always record the show and watch it later. most cable providers these days come with the option of having a recorder, so if you haven't got it yet, you can get one. or check for the repeat telecasts to see when it matches your baby's nap time.
