Marla, I did it with my child, I let her scream one night for I think an hour or more, then the next night it was less and then less until no more crying. It really worked and I'm so glad I did it. But let me just say it was extremely hard to listen to. It did not stress my daughter in the way that she needed more meds. She is now 6 and has had some crying fits, I never worry. As far as the injection goes; You should not only learn how to give the injection but I feel it should be with whoever has your child at all times. And of course anyone who is your childs care giver must know as well. In some cases this is life or death. Please consider this. Good Luck!Linda
