DS is 2.2 yo, we speak german and dutch at home, whilst we live in the uk. His CM and the rest of the world therefore speak English with him. He is a very affectionate, cheerful toddler, but I see more and more that his understandably slower development language-wise frustrates him very much. How can i make things easier for him? Conscious that this is a very broad topic, maybe any suggestions of books that might be helpful for me to read up on this? Many thanks!
