Are your kids learning Chinese happily (international sch kids)

I want my girl to study in international sch. Some sch provide few Chinese lessons a week , some provide more Chinese lessons, say everyday. I know I have to give her extra Chinese lesson outside the international sch. But being an international students she may find learning Eng is much easier than learning Chinese and I think she may not willing to learn Chinese. Are these the truth?
