My sisters DD goes to kindy and it is basically a social thing for her. My DS1 who is a year younger knows more colours, letters, can count to twenty, speaks more clearly and has a larger vocabulary. This could be because my son has been to daycare since he was little but he has thrived and developed faster than my niece who has a SAHM. Please note I am not trying to be offensive to SAHM but my sister (a wonderful mother I might add) simply does not spend the time like they do at daycare on those things.
