I tend to have Radio 4 on all day most days, I enjoy it. Since I've had DD I find something on listen again turn it off if there is something with an unpleasant or disturbing atmosphere on, but other than that it's never occoured to me to censor it at all .
DS (6 weeks) seems to find it calming and it's doesn't seem to bother DD either, but she's 20 months old now and understands quite a lot. After something DP said last night I'm wondering if I should stop listening to it so much. I'd certainly never randomly leave the television turned on when she's around but I'd never considered that wall to wall speech radio might also have negative effects too. TBH if I've thought about it at all it's just been as another way of normalising English (DD's bilingual and we live overseas).
What do you think? Is it a Bad Thing (repeated news etc)? Do I need to cut down? I really hope not...
