All of a sudden we are having a lot of unexplained, stubborn lows. Does anyone see this in their child prior to getting sick? Historically, my daughter always runs high, so this is new. My other thought is we are on a new pump and the delivery on it is slower, making the absorption, IMO, much better. So obviously another thing to look at would be to do some tweaking if it continues past today. Nothing new in her routine. Any other thoughts?
