What's the difference between "nursery", "kindergarten" and "child care"?

Kindergarten is when a child is officially enrolled in a normal school. It is the first step of formal education with a standard curriculum while nursery and childcare are more of a learning and/or daycare centers where children can also learn early education with no standard curriculum. 

Nursery is for when the kid is a baby

kindergarten is for when the kid is 5

child care is day care, for when you're out and have no baby sitter.

Thank you , the question's area is some how not related to insurance , therefor unable to answer.

Best wishes

nursery of the first the birth of the child to 3 years, kindergarten from 3 to 5 years,  child care be one year pre the first row Elementary school.
