This is an article we highly recommend you read. Summer boredom can be a great thing for kids. Boredom can actually help a child become more self reliant.
"This is the sweetest little school! We love everything about it, from the Montessori method that has opened up the world to our daughter, to the fun, loving, yet disciplined atmosphere the teachers and staff foster. The children learn respect for others as well as self reliance on themselves. I can't say enough about how fantastic our experience here has been for all 3 years! We look forward to sending our son here when he's old enough."
