Hello and welcome. Sorry you have to be here. My son does not have Down's or celiac...I do read a lot of posts in the Parents section that talk about celiac...so someone should chime in sooner or later.
You might also want to post specific questions about the pump in the Parents section...you'll get the most readers there.
My son has been pumping for more than a year and a half now. We started when he was 5. Best thing we ever did. For us, it provides more freedom and flexibility, and much more precise control because of the small increments of insulin you can provide.
As for detecting lows, my son was not really good at that for the first year after dx, but now he is right about 80% of the time. He always says he feels "shaky." For a while, it was his hunger that alerted him. Again, if you post a more specific question...I'm sure you'll get more of the answer that you want.
This is just the best place for advice and support. You are so not alone...and there are so many people here who will guide you through these difficult first months and provide you with great tips and a shoulder to cry on. We've all been where you are and are here to help. Let us what we can do. Look forward to hearing your and your son's story.
