We never left our CAH babies/toddlers with teenagers, but I do agree that it is a very personal decision, that you must base on the responsibility level of the babysitter, your own comfort with the situation, and the child(ren). Having lost a CAH child, I think that I am probably over-sensitive on this issue, but that’s just how it is for me. Having time together for our marriage is a number one priority for my husband and me, and we have been very blessed to have several, capable adults who have been willing to babysit since our kids were babies. A couple of months ago, (non-CAH son is - 9, and CAH daughter is - 7) for the first time, we took a 17 yr old that we trust with us a few months ago, and had our nurse practioner instruct her as to where and when to give the shot. Personally, I’m not so concerned about the responsible 17 & 18 yr olds (some are more responsible than a lot of adults I know!); it’s the 13-14 yr olds that are so sweet and have "just finished their babysitting course", that I do not think are generally mature enough to handle that kind of emergency situation. We also make use of cell phones and pagers - peace of mind makes for better "date times" for Mom & Dad!
