Any mandarin class to recommend for toddlers?

Hi there, this article recommends 3 centres/schools in Singapore that are piqued as some of the top places for children to learn Mandarin. http://sg.theasianparent.com/chinese-enrichment-classes-for-kids-which-class-is-best-for-your-child/ One of the schools mentioned is the Berries Language Centre, and one of my friends has her daughter enrolled in one of the centres branches. She is impressed by the improvement her 3 year old has made and she highly recommends it to other parents.
