Are you a working woman? Aap kahi par kaam karthe ho ya..kaam Karna chahthe ho? Agar haan tho, 1 year 10 months se usually play school start hotha hai. Koi even 1 and half years se bhi admission lethe hai. If you are housewife and can take care( or you have someone else to take care of baby) better you join directly to nursery at the age of 2 yrs 10 months.
