Hi Lisa
I really feel for you. Your whole world has been rocked, you are in the right place here as we understand that and 'get it' where most of your friends won't understand totally, this is normal.
Having a toddler with diabetes is damned hard work and reading your messages you are doing so so so well, you really are, don't underestimate yourself.
I've been where you are. My daughter was diagnosed as a 5 week old baby with type 1, she had her pancreas removed a week before so she was made a type 1. So I totally understand how hard it is.
You may have been told to aim at levels under 10.0 or 12.0. I will be honest and say this is ridiculous at this stage for you. You do need to avoid the highs and lows if you can but with a child on injections you will inevitably get both highs and lows. When you say you just think you have it under control.......... I used to think this but only for a while. It took a long time to accept the fact that with children you can never get it under control. You will get to a place where things are going ok ish but then they change again. With a toddler its even harder because of the energy they have and the brain power they are using. You really are doing brilliantly you know.
As Bev said the only way you will get anywhere near good control will be on a pump. Look into it, it is worth it. If you decide you like the idea and it will give you better results, its hard work but better levels then don't be fobbed off by medical people telling you your child is too young or you need to give MDI (what you are on) a much longer go. That is all rubbish.
Take a look at
www.childrenwithdiabetesuk.org it is written by parents for parents. It has so much information on the website to help you. You can join an email group from the home page which is a busy email group but it is a lifeline. It is my lifeline and I wouldn't be without it (bit like here but that is purely for parents).
Any questions you have, ask. Remember no question is a silly question, we have all asked them.
Take care
