Hi mintiemint,
I have two boys 4 1/2 & 1 1/2. My older son did the same stopped using Chinese after he started nursery at two. We are happy to have play dates with your son. My boy speaks Chinese well when he plays with Chinese speaking kids. Pm me if you'd like to get together. We live not far.

I am a Malaysia Chinese speaking mum with a 2 1/2 year old boy looking for a mandarin speaking playgroup. We live very near to the Wandsworth park.

I always speak mandarin to him, but he starts replying everything in English since I put him into nursery twice a week a year ago. I really would like him to keep speaking mandarin.

I would like to know if there is one Chinese playgroup here, if not I would like to start one myself.
