People say that as you age it gets harder and harder to learn.
From our experience we can say that children learn languages easier and faster when they are younger. At this age (between the age of 2-7) children are very curious about all sorts of information. They are open to the world and absorb everything easily. We feel that by teaching and playing in English allows the children to learn by experiencing naturally as they would learn their own mother tongue. Learning in a multi-cultural environment also has its advantages: Children speak to each other in different languages, due to cultural differences they learn to accept and respect others.
The children will be more understanding and will have more empathy for others.
