Write daily keeping it simple. Send the sports or comics from the local newspaper, a cute card, a package with a word game, etc. Prepare yourself for your child going off to camp. Kids need to know what they are taking to camp. You need to let them help you with the packing.
Every camp sends a list of things to bring to camp.
Follow the list. Don't buy expensive clothing for camp. Take extra socks. Take old shoes, gym shoes or hiking boots. Take a laundry bag, rain poncho, water bottle, sun block, insect repellent, flashlight, shower supplies and toiletries.
