You can check around, but finally depends what kind of nursery you are looking for., you need to personally check by yourself and even better with someone whose kid has been there to be sure of the standards. You will find quite a few small private (run from home) nurseries, Now there are few more authorized nurseries too. My 3 year old has recently joined http://tskqatar.com/ and is happy so far after the first few days of nervousness! Staff is Indian which is ok for me because ultimately kids will study in English so you don’t need to look for keralite !
