This may be true. See the website again. There is a lady there whose
girl child (now 16) started pumping at age 3. I believe there
are several new members of the mailing list who have kids in the 7
to 10 age group who either are pumping or will be shortly.
As I see it here is the problem. One must be able to carbo count
and to properly calculate the required boluses, and adjustments for
high or low blood sugars. You must be able to run a simple
calculator and do fractions. If you can do that in a routine manner,
you can manage a pump. My daughter Lily, at age 11, was able to
manage routine boluses for food and figure out the carbo content.
High or low blood sugar management involving projecting the effect of
unused insulin in her body was difficult for her until last year.
Now at 14, she manages everything herself. It is my opinion (that of
a non-medical lay person -- an engineer ) that a child younger than 9
or 10 probably needs a lot of help managing the insulin doseage.
That is only because when you use a pump, you are freed from the
fixed carbo intake at fixed times, your schedule is no longer fixed,
and thus your insulin requirements become highly variable. One
could, of course, use a pump with the better control and still
maintain a fixed schedule -- probably your control would be better
than ever. But, part of the reason to pump insulin is to re-gain
those freedoms. Personally, I would do it for my child at any age,
now that I have several years experience with Lily. I probably would
have been more hesitant had Lily been younger but now I see the
results and I do not hesitate to encourage you to move forward. The
only advice I can really give is that one of you (not both) will have
to become the child's pump mentor, to be available always to answer
questions, do calculations and manage the diabetes on a day to day
basis. The docs and health care team see the patient far to
infrequently to be able to do this for you or even give you good
advice on dosage. You must determine these things yourself and it is
not that hard, just tedious.

Going on the pump will drop this into the 7's immediately.
Using Humalog (but not immediately) will further lower it into the
Lily eats cake, ice-cream, hamburgers, fries, etc... even candy bars
(after all the carbo is printed on the label) all normal food with
no artificial sweetners except for diet drinks instead of sodas or
juice (by the way try Sunny Delight LITE 7 grams per 8oz). She is
moderate with the cake and pie, usually no more than 30 or 40 grams
of carbo at a time. Her hbA1c's are always in the 6's since she
started Humalog in her pump.

This is just as complicated if not more so than using a pump.
I bet you no one has actually measured her basal requirements,
insulin to carb ratio and insulin to blood sugar ratios.
I will shortly have an article on the website detailing how to do
this. It will be geared toward pumpers, but any diabetic could do
it. The same way.

That seems like a bunch of insulin to me. Lily, 5-2 110 lbs uses 1
unit for each 66 points. Many adults on the list use 1 unit for 50

Not anymore. But for a young child, management is just as necessary
as with injections, more so with more freedom, they go hand in hand.

Of course, she is diabetic! It has little to do with the pump, you
can simply solve the problem faster with a pump and help to prevent
recurrence. i.e. if you eat something that has more carbo than you
thought, you will get high, happens all the time -- doesn't matter if
you pump or not. The same is true if you take more insulin than you
should have for the food you eat. Your gonna get low. Eat glucose,
turn off the pump for awhile.
