There is a health store on Yik Yam Street in Happy Valley that carries them. I forgot the name of the store, but it has the word Health in it. It also has a store inside Citysuper in Times Square.
I found this pharmacy in North Point that carries most of the Aveeno products including the baby line. Their phone number is 2563 3930, you can call and ask if they have the product you are looking for.
