12 YR DS on MDI Hum/NPH Breakfast he was 236 - gave 1u hum and his usual 7NPH with breakfast ( ate 2pc French toast, milk and pear ) his ISF is 110, just got a call from school & he's 50, and going down quick he says - so now were doing juice, cheese & crackers....is it unusual to have different ISF at different times of the day?

yes, absolutely. Most of our kids need more insulin at breakfast actually. it's harder to tell which is responsible though - the NPH or the Humalog since right about this time they're overlapping (the humalog is tailing off and the nPH is gearing up)

Well I can't tell you much about NPH and ISF, but on the Lantus, Levemir or Pump regimen, it is not uncommon to have more than one ISF. We have three.:)

I think I've read a formula here to help figure out ISF....any suggestions on how I would figure out different ISF's for different times of day? I've asked the endo about switching insulins but she thought since we were going to the pump in June (omnipod) that we shouldn't try to learn a new insulin if were going to change anyway? That seems to contradict a lot of the info posted here??

I think the formula only applies to a Lantus, Levemir, or pumping regimen, but Wilf uses NPH and figures out his daughter's ISF all the time. In his particular case, I believe he uses the 1800 Rule. That will get you one starting point ISF, but it will probably have to be adjusted from that point on (pm Wilf for more information).

BTW, many of us have gone from a carb counting regimen like Lantus to the pump and it does help substantially to reduce the learning curve. I know in our case, if I had to go from NPH to the pump, I would have had much more of a learning curve, than going from Lantus to the pump. However, since you're going to be pumping rather soon, it probably doesn't make much sense to do a transition over to a new insulin if it's only going to be for less than a month.
