I purchased the Grolier products worth USD 1000 for my 8 months old twins. During the purchase the salesman confirmed that he will provide good support and suggestion about how to use these books with toddlers.
Later on my babies gave me really tough time while I was trying to teach them with those books, so I called the salesman (many times) to suggest some tips and tricks. But the salesman kept on saying that he will send some emails about it, but did nothing.
So I will not suggest anybody to buy this expensive product for your toddlers, without the guidance, it’s a total wastage of money. It is better to buy some other useful product.
