As a teacher, I see every day the tremendous positive effects that reading regularly has on multilingual children. There are so many books out there to choose from, but it can get pretty expensive to buy so many books, mostly if you speak several languages at home. The good news for multilingual families is that for this age you don't need to have a whole library of books in each language. You can use the same books to expose your child to different languages. It is also not necessary that you read every time exactly what is on the pages. You can just do some storytelling and leave some parts out or add some phrases if needed. You can even make up a whole new story using the images that the book offers.
