Hi, My name is Neha and I am moving to Shanghai with my husband and 2 year 4 month old son next month in april. Right now I am living in Belfast, northern ireland but i am originally from India. My husbands office would in Quingpu district, so we plan to stay in Puxi. Can anyone please recommend me a good schooling option for my 2year 4 month old son. What is best - international schools, kindergartens or pre primary schools. If you could share the details about the same, that would be much appreciated. thanks
