Contact the camp ahead of time and ask for a list of recommended clothing and apparel. The camp staffers know the terrain and weather patterns, so they'll have plenty of solid suggestions. Find more tips at the American Camping Association (acacamps.org). Find out if your child needs clothes of a certain color for field trips, religious services or team sports.
Begin packing several weeks in advance to avoid last-minute shopping trips or scrambling for a must-have favorite shirt. Your child should help you pack so she knows what she's bringing.
Purchase or borrow a large duffel bag, a traditional trunk or a trunk on wheels.
Put your child's name or initials on everything--clothes, hat, swim suit, towels--with either a laundry marker or iron- or sew-on labels (available at NameLabels.com and other sites).
Pack a small toiletries kit or basket so your child can carry and keep track of essentials such as soap, shampoo, toothpaste, toothbrush, floss, deodorant, comb and brush. Flip-flops for the shower are also a must.
Pack sufficient clothing. Depending on where the camp is located, even in August the nights can get cold. Include a fleece jacket, a windbreaker, a warm hat and gloves. Pack rain gear in case of wet weather, and bathing suits for swimming.
Pack additional necessities. This could be games, toys or books. Also, choose between cameras--film, disposable or digital. Pre-stamped, pre-addressed postcards are a great way to encourage kids to write home (and at no cost to them).
