Hiya Ruth
You will be fine. I understand the nerves, I was nervous but excited.
It is hard work to begin with. I think it is more work than MDI but you don't really notice as it just becomes easier with time as the diabetes will change.
It is like getting diagnosed all over again but without the same heartache, this time it is practical stuff.
You may be one of the people who want to chuck the pump out the window in the first week. Don't do that. Get through that knowing it will be better.
This will change your lives. It will change the life of your little boy to become a better life, so much more freedom, people look at me madly when I say that because they is the box with a tube they are attached to 24/7, believe me the kids don't notice the tube and they are proud of their pump or pancreas on the outside 🙂
You will be so much more in control as it is an hourly thing, you can change things that concentrated in hourly increments if you so wanted to.
He can eat when he wants to.
However you need to get the basals right first. Most important the night times are sorted and the day times will then fall into place. I'm hoping your DSN or whomever will be calling for you for a few days to do some tweaking for you.
Ask anything you like. If I'm not around, then email me, I think it is on my profile, am sure it is. Am happy to help 🙂
