Your child’s age is just one factor in determining his readiness for camp. His maturity, comfort level with new situations, ability to get along with others in a group environment, and willingness to follow instructions are also important factors.
Many camps are designed for specific age groups and will only accept children within this range. The age requirements are often higher for specialty and overnight camps than general day camps.
Most school-age children are ready for a day camp environment. When in doubt consider a half day camp or a series of short summer classes (art, sports, etc.) to test the waters.
Overnight camp can be a big step for children. In general, children should be at least 8 years old before considering overnight camps. Before going to overnight camp your child should be comfortable spending the night away from home. Do some test runs at friends or relatives. She should also be able to get herself ready for the day and for bedtime without help, including changing clothes, tying shoes, brushing teeth, and showering.
Perhaps most importantly, your child should be enthused about going to an overnight camp.
