Yesterday I took my little girl for a hamburger and then she had a few little cookies and milk when we got home. Her BG was 8.9 before the burger at the restaurant so I boluses her appropriately and then enjoyed our dinner out. I didn't check her again for the cookies and milk at home as it was only an hour after the dinner bolus so I just did a straight bolus to cover the carbs. For no reason other than intuition I decided to check her BG a little while later (an hour and fifteen minutes after the dinner bolus) and her BG was 28.7!!! Lifted her shirt and saw that the infusion site was out. I got a new infusion set in and bolused her for the previous meal and snack. Checked for blood ketones and she was 1.4! I was surprised how quickly the ketones had accumulated. She was back in range and had cleared the ketones by 3 hours later but it was quite an experience to find out how very quickly things can go badly without the insulin. It also reinforces our belief to check her frequently no matter what the endocrinologists say about only needing to check a few times a day. If I hadn't randomly checked her at that time she could have been VERY I'll by bedtime snack time.
