How tough is it to say goodbye to your child for a year?
Excrutiating.
How did you handle it?
Poorly.
Here are WV Mom's tried and true tips for parents of outbounds:
1. Talk to your kid every single bloomin' day. I did that, and when their friends wondered if that wasn't limiting their "cultural experience," my kids would look sad and talk about their mom's mental illness.
2. Remember that if they weren't there, they'd be in college, doing what you did.
3. Thoroughly clean their room the day they leave. You grieve as you immerse yourself in their essence, but you also get pretty pissed by what you find. Which goes a long way toward erasing your grief. Don't forget to look between mattresses (which is where rookies hide their stash) and in their outlets and wall switches (for the more advanced).
4. Find a pen pal whose kid is on exchange and be sad together (I love you, Sandy!). Make sure your pen pal knows the answer to everything is, "You're right, everyone else is wrong, and I'll inflict great bodily harm to anyone who says otherwise."
5. Adopt a martyred look when you talk to parents of nonexchangers and talk about how lucky they are that their kids have no sense of adventure.
6. Amuse yourself, and make your child feel more at home in their country, by making friends with their host mom and teaching her to say, in English, "Are you bloomin' kidding me?! What in the world the matter with you?! You knew better than that the day you were born!! You are so totally out of the will!!!"
7. Become a regular on this board so that (1) you can get the support you need and (2) you can keep your mom-skills sharp by yelling at exchangers who are being stupid.
There's more, but that will get you started.
