Hi Ness. My son was 3 when he was first diagnosed and i sure do remember the tough place you are in right now. With time it does get easier! Like you, we had to hold my son down first of all for his injections as a nice scar on my arm will prove when i first discovered how strong his teeth were! However, it will soon become the "norm", and it will all settle down. At the moment you have so much going on. So much to do, so much to learn and so much to take in! It is a really steep learning curve and very confusing but you are off to a good start as it is always good to question everything. My little lad was a skinny 3 year old and my Diabetic Nurse really just pinched the skin and said that was fine as there was enough fat for the needles. So tum, bum and arms were fine. He didn't like the legs so much as they have always been quite skinny and i think he would tense quite a bit which would have hurt him, so we avoided it more than the other areas. Might just be worth asking the nurse to pinch the skin where you would like to do the injections and just ask if they think there is enough to inject. You will then have a better idea and can then rotate the sites. Different sites also have different absorbtion rates for the insulin and the bum is often one of the better places for a more stable release of the insulin which is quite helpful whilst going through the "honeymoon", stage. Try not to let it get you down as it does get easier!
