If a child is growing up with two languages (for example, Cantonese and English) and she sometimes uses English words when speaking Cantonese or vice versa, is she confused?
Children will use words that they know rather than not say anything at all. For instance, if a child knows the word for ‘ice cream’ in one language and not the other she will use the word in the language she knows rather than not ask for ice cream at all. The child is not confused; she is simply making use of all the language she has.
