Hi Paul,

Here's an article on Education.com that will offer insights into your question and others relevant to this stage of your child's development and education...

Choosing a Preschool or Child Care Center for Your Child

Another resource I would recommend you review is the Preschool Readiness info center found here:
http://www.education.com/topic/preschool-readiness/

Regardless of start age, most preschools and pre-K programs require the child to be potty trained before enrollment (or far along in toilet learning development). The Preschool Readiness info center has potty training articles, as well as an offer for a free potty training kit from Pampers.  

I would also suggest that you review the expert and parent answers that other parents with the same or similar questions received in JustAsk:

http://www.education.com/question/age-child-typically-preschool/
http://www.education.com/question/start-preschool/

Lastly, contact the preschools and pre-K programs directly to find out the enrollment policies and age requirements specific to each school. My experience when enrolling our daughter in preschool was that there was a lot of variance across preschools or not the same start date across all schools I called.

I'm also including a resource to support your family with your child's current developmental and learning stage.

U have to wait to ur kid be atleast almost 3 yr. old but needs to be potty train, need to check ur closes school or early child program if u have one where u live.
