Trilingual children?

Unfortunetly I know what you mean and have had some experience of this. I have read before that children under the age of 3 and a half aren't supposed to have too many languages spoken to them, only one mother tongue should be focused, or else they would end up like this little girl - understand most things but only able to speak a few words. My goddaughter's father is French and her mother is Chinese, they speak English to each other and a mix of all 3 to her, and on top of all that they hired an Indonesian nanny who is actually under the mother's order to quip in Indonesian to her here and there. Now she is 4 and had only just be able to learn how to speak (barely) properly in English with a language specialist. Needless to say they felt pretty worried too. Try researching this and I suggest that in the mean time only speak one language to her.
