I noted that someone mentioned using a pump to administer Cortef. Can you tell me more about that? Does the child have to have a hickman-like needle inserted? Do they carry a bag of liquid Cortef around, attached to them somehow? We get labs at least every 3months and sometimes 4weeks, we are constantly changing dose; does the pump help them stay regulated better? Is it mainly used for salt wasters? Has it helped with overall energy & weight?natalie rechner
