If you think he's more comfortable at home with you, then you do it. You kind of have to get over your squeamishness as a mom - it's tough but it's part of the deal. Otherwise, call the pedi and see if the nurse can do it - you don't need to see the doctor. It might be cheaper too. The nurse and the office are familiar to your son and may be more relaxing than the ER situation was. I would think Visiting Nurse is a little more arranging than you need, and more fuss than your son needs.
