If I may tell a little story on myself (mom here). . .
During BCT blackout I busied myself learning every little thing I could about how I could help my son. I scoured WebGuy, I read every FB Parents page post, and I became particularly obsessed with 1) sending him a robust first aid kit and 2) making sure he had the second monitor and appropriate cables for his issued laptop. I went to Target and bought every time of OTC medication that I thought he might possibly ever need in the exact size plastic bin that the parent on FB had recommended and shipped it after BCT - I mean this kit had everything from Motrin to Immodium to Vaseline for skin rashes. My son's response to me was, "what the heck do you think goes on here Mom?" Apparently, he and Dad skyped and had a good laugh about it. To this day, I still try to save face and say, "It's all sh*&@ and giggles until someone needs an Immodium, then you'll thank your Mom." The cables and the monitor? Oh yeah, he just went and bought those - because he is and was a high-functioning adult. We didn't have any tearful phone calls, he made great friends on day one. Every story is as different as our respective families. We will head out for graduation soon - I'll have to remember to ask my son if his first aid kit came in handy. . .
The moral of these stories: The parents are getting trained also.
It's okay to be a little nuts (there are our babies after all), but try and keep it in check. My favorite saying: be a fly-by parent instead of a helicopter parent.
