Hi, I just wanted to add my opinion - which seems to differ from most of your replies. We noticed our son (waiting on Ambry Genetics CF results) who is 20 mos. was peeing and drinking a lot. We too, assumed it was normal. After a few weeks of this, he almost died. He went into ketoacidosis and was diagnosed with type 1 diabetes. My point is, you're the parent, which means - you're the advocate. Get tests done sooner, rather than later. Good luck.
