My LO is 2 years old. We live in Italy and I speak to her in English and DH speaks to her in Italian. At the moment she speaks predominantly English as she's with me most of the time. She speaks in 5 or 6 word sentences, has a wide vocabulary and really good understanding. Her understanding of Italian is very good too and when prompted she can say quite a lot of words and the occasional 2 word sentence. She spends 3 afternoons a week with my in-laws while I'm at work and she continues to speak to them in English even though they don't understand. She's beginning to get more and more frustrated that they don't know what she's saying and it's hard for my in-laws too. I know that eventually she'll work out which language goes with who but I was just wondering at what age other people's LOs did this, more so I can reassure my in-laws apart from anything else!
