My 14 year old daughter was dx 02/19/2009, Our highest A1C after release from hospital has been around 6.3. We went on the One Touch Ping in April 2010. Alexa loves it. She really disliked the shots but loves the pump. She is very active in volleyball. It does give her alot of freedom. However, we are still learning to adjust the basal rates for her activity. It definitely is a work in progress. The biggest problem we have is the lows. She experiences the 6-8 hour exercise lag. We have figured out the basal rates and boluses for single game days. But, we are struggling with tournaments. She has to eat alot to avert the lows. But, the more we have, the better fine tuning. (By the way, a bolus is the insulin given through the pump for a snack or meal, much like the shot. The Basal rate is the amount of insulin that is infused every three minutes)
Although Alexa is rather responsible, at her boluses and taking blood sugars, she does not keep a log book outside of the pump.
Overall, the lows are a concern until you get the right settings. I have a friend that recently went on a pump and she hasn't had many lows since the initial fine tuning. However, she is not very active athletically. I think Athletics is a little more difficult, but the benefits far out way the consequences.
Also, since your school doesn't have a nurse, I recommend that all the teachers are made aware of symptoms he exhibits when he is low and how to help him. Each of Alexa's teachers has a fast acting sugar and a slow acting carb in their desk in case Alexa needs something.
I hope this helps. Blessings on your decision.
