My ds is 3.1 and I am English and his dad is Dutch , my partner and I speak English together and he speaks Dutch to my son and I English. We are living in Dutch speaking Antwerp, and ds attends a Dutch school.
He had a wide vocab of words and can make himself understood enough to bargain with me about in which order to do things etc.
His teacher says at school he is still speaking English and Dutch and not solely Dutch and seems to think that by now he should only be speaking Dutch at school. Is this correct - how can I help him to speak Dutch only at school he has been at the school for 6 months now.
I am worried because the teacher says he is getting a little frustrated when the other kids don't understand him. Any advice more than welcome.
