You're sending your child to camp to get the ultimate childhood experience — don't make it hard for them to enjoy their Summer by essentially giving them an out. If your child is the least bit homesick — and you've told them that they could leave upon having those feelings — leaving is going to be the first thing they want to do. Encourage your child to have fun, make friends, and learn new things. If you're really that concerned about them being too homesick, maybe they're not ready for sleepaway camp.
(Conversely, if you're the one that's worried about missing your child too much, try not to project those feelings on an otherwise excited child.)
