My DH and I have different mother tongues and we live in a 3rd language country. So DD does not get much exposure to either of her 2 languages. Is it a good idea to use DVDs to increase her exposure? She is 20 months old and hasn´t seen any DVDs so far. I´m a bit worried about letting her watch TV so young but wonder if benefits may outway the disadvantages. Her language skills are a bit delayed.
