When reading the "what number are you comfortable with" thread, I was surprised to read that most people will treat a BG number in the 80s and 90s while on pump. DD hasn't started the pump yet so I am inexperienced. But the thing I was looking forward to was, if when checking overnight and she was in the 80s or 90s, I thought I could just lower the basal to prevent her going lower. But in this thread, I am reading that people are "treating". So when you say treating are you actually giving carbs, or do you mean treating by using temp lower basal. On another note, would it be advisable to just use a lower temp basal if you notice your child in the lower end of range overnight, or is it imperative that you treat with carbs as the temp basal will not be sufficient?
