"I credit a lot of their fast pace of learning to attending class twice a week...There is really a huge difference that can be seen in a short amount of time."
Will my child get confused by different or multiple languages?
No. Children store languages discreetly in their brains and can learn as many languages as they are exposed to. That being said, it doesn’t mean they won’t mix up a word or two (e.g. “I want more agua”), it just means they are not confusing the language.
