The pump is a whole different regime to MDI what your daughter is on. It will indeed change her life and yours as a family, the freedom it will give you is amazing, its hard work to begin with but we wouldn't change back for love nor money.
It is unfortunately a proven fact with studies taken that most children do not wake up when hypo at night. If a child does then that is deemed to be lucky. Most of my friends night test and always have done. I think if you don't night test then it needs to be an informed choice ie you need information as to why you do and why there is no need to.
We have used the Medtronic pumps for over 4 years. We now have the VEO and we have full time funded sensors (the attached CGM). It does and can with understanding and knowledge, change things for the better. It is proved that using them full time can lower the HbA1c and you can react to what you see using the sensors.
Medtronic have just brought out their latest sensor which is allegedly proved to be 98% accurate with hypos. We are trialling a box of them in a few weeks so can report back then. So far what I have heard and I have a few friends using them, that they are absolutely fantastic.
A pump is nothing like being on MDI. There is no long acting insulin used, it is just Novorapid or Humalog. The back ground insulin is replaced by novorapid being delivered constantly by trickling in over a 24 hour period. You have to set up different rates of how much is trickling in. For example at 5 am to 9.30 am my daughter has 0.95 unit trickling in per hour yet at 9.30 am it pulls right back to 0.10 unit per hours. She has 9 different rates throughout the 24 hour period and you can tweak it when you start seeing patterns of highs and lows.
On top of that you then give novorapid through the pump as well (all from the same reservoir) for carbs eaten.
It is easier to control levels as to what food does. I know that for Jessica when she eats pasta she spikes about 5 hours later. You can set up an bolus of insulin to cover that food so that it deals with that spike.
Take a look at the INPUT website, they have lots of info on pumps and also the
www.childrenwithdiabetesuk.org site which has lots of info. On the Medtronic site there is a pump school video to watch which is great.
Getting funding for the sensors is getting harder but some PCT's and even GP's are still funding them.
