My child has a summer birthday, is that OK for Kindergarten?

My child has a summer birthday. He turns 5 in June. Is that still OK to start kindergarten then?
I would not recommend holding a child with a summer birthday out of starting Kindergarten this Fall. If you are worried about your child and he or she is notably more immature than other children at the same age, talk to your child's preschool teacher for additional guidance. Generally, I would not recommend waiting a full year with summer birthdays.
