看看经验丰富的国外夏令营管理者是如何说的。
孩子|宿营者 Camper

去夏令营之前在别人家过夜几晚，别睡在家里。家长要控制自己给孩子行李打包的冲动，或者不停问孩子在别人家过夜的情况。如果孩子有电话，把电话放在自己家里，这样可以防止孩子老是给父母打电话。

参加夏令营之前，教孩子学着写信，平安信。到时候孩子说不定会从夏令营给你写一封信。
体力上提前准备。如果你专门买了山地鞋，穿着它们去散步。
对于青少年，让他们远离手机和电脑游戏或者IPAD一段时间。哪怕是几个小时或者一个周末。
让孩子们在自己的微信朋友圈里写下这么一段话：“我要去参加夏令营了。会远离微信一段时间。”

要求孩子写下他们的目标。
Plan several sleep overs. Resist the urge to pack their bags for them or to check on them while there. If they have a phone, have them leave it at home. This is a good way to practice not having direct or constant contact.
Have them write a good ol’ letter to someone. You will thank me when you receive a letter from camp!
Gear up physically. If you have purchased hiking boots, break them in with a long walk. Especially for teenagers, have them take a mini-vacation from their devices. A couple of hours or a weekend.

Have them write a statement for their social media pages. “Peace out Facebook, I won’t be sharing my day-by-days with you, I will be at camp.” Your teenager may not post that, but maybe something like it. Have them write down their goals.
Make a homesick plan:

Homesickness isn’t entirely bad. It’s great to love your home. It’s sometimes part of the process, and it’s a confidence booster when a camper gets through it.

Make a happy place plan and write it down. This is an amazing opportunity to learn a life skill. Today’s youth go to technology to escape, and studies show this increases their stress. Some ideas might be: taking 10 deep breaths, traveling to a happy place in your mind, packing a certain stuffed animal, shooting hoops, or tossing a football. They are capable of this independence.

制定一个想家应对方案： 想家并不全是坏事，这是爱家的表现。有时这也是成长的一部分，一旦克服，就会自信大增。
拟定一个快乐计划，并且写下来。夏令营是一个很好的学习生活技能的机会。如今的青少年都喜欢躲避到科技中去，研究表明这反倒会增加他们的压力。这个计划可以这样写：
做十次深呼吸；
闭上眼睛幻想自己到了一个快乐的地方；
带上一只玩具熊；
射镖；
踢足球；
他们有能力独立。

你的计划千万不能这样写：
“去夏令营试两天，如果你实在不喜欢，我们就接你回来。” 这样做只会让他们坚持一两天，然后自信心就没了。

让孩子知道和父母之间的电话微信交流会是个什么样子的。你不需要每天给他们微信电话问候，但让他们心里有数。
Your plan should NOT be, “Give it a couple of days and if you don’t like it, we will come get you.” This will set them up to give it a couple of days and knock the confidence right out of them. Let your camper know what to expect with correspondence. You don’t need to write everyday, but let them know what to expect.

你自己 | Yourself

You are giving your child an incredible gift. I cannot promise you that they won’t lose some socks, that they will love every meal or activity, and that they will adore every counselor. But you are preparing them for college and beyond; you are giving them the freedom to gain confidence, independence, and leadership skills; and you are instilling in them that they can do it.
送孩子去参加夏令营是一个很棒的礼物。虽然我没办法保证在夏令营TA不会丢东拉西，或者报告说他喜欢夏令营的食物、活动，他们也许会说夏令营的老师领队不好。但是你们是在给TA上大学做准备，让他们现在有机会获得自信，独立和团队精神；你在逐渐向他们灌输 – 他们能作好。
在孩子的行李包中放一封自己写给TA的信。 和孩子告别时，不要哭。除非TA看不见你了。深呼吸一口气，相信自己，提醒自己这样做是送给孩子的最好礼物。

Pack self-addressed envelopes in their luggage.
Whether they are flying or driving, refrain from bawling until they can’t see you. Take a deep breath, trust, and remind yourself that you are giving them an awesome gift.
