I agree here with most, stamps and stationary was all my daughter could take to bootcamp. the calling card came later, about a month in before they could call us. but she got thru it with the daily letters from home, I sent one every day and sometimes she would get 2 at a time. But she was happy hearing from us. she wrote every sun, about the only time she had down time. after that first month, they could have snacks, and yes, they share. but they dont have too, it is just something they do. I would send the flat rate boxes, with some snacks to share and in the bottom, marked open in private, her favorite candy to hoard and eat all herself.
