i used to when ds was a lot younger, then one day he started clapping along to the audience and made me think that he was perhaps paying ALOT more attention to it than i realised
now it really is no tv or a couple of ds's programmes. when dh is home he is always watching things that are inappropriate for our son. just because they dont swear doesnt mean it is appropriate, he likes things like stargate, yeah it doesnt scare me but the guns, some of the aliens and some episodes in particular would have given me nightmares at even double our sons age, it all came to ahead when our son did in fact start waking in the night screaming, crying and shouting daddy in such a scared voice.
dh's response previously oh he isnt even paying attention, errrr he obviously was, he doesnt argue when i tell him to turn it over now, honestly men can be sooooooooo blind sometimes! i mean one time i walked in and he was watching a film about gangs and jonny depp got shot in the back of the head and you saw the exit wound and all the blood i went balistic because once again our "unattentive" son was absolutely glued to it - he had another nightmare that night
anyway my long winded response is i genuinely do think that they can be affected, yeah ok possibly not newborns and a couple of month olds but as they get increasingly older you do not realise what they pick up, even if it isnt the words they are coming out with they will form an attitude or opinion that it is acceptable to talk to people like that you know?
i have sky plus so went through a phase of recording my programmes and watching them during ds naps - best of both worlds, i still got to see my programmes but ds wasnt watching anything potentially inappropriate
