Rosie has been active in several sports since her diagnosis: softball every Spring, Taekwondo for a few months, and one season of basketball. For each of those activities, she was comfortable leaving her pump on, as long as she was wearing a pump belt that zipped shut rather than using velcro. (She worries a lot when she wears her one belt with velcro compartments, so she very rarely wears that one.)
Last week, she started cheerleading practice. This is new territory for us- I was far too shy to have ever been a cheerleader when I was her age! She's very excited to join a few of her friends in cheering for the boys' basketball teams at her school.
The first practice was an hour and a half, and I stayed in the next room the entire time. After about ten minutes of jumping and kicking, Rosie came to tell me that her pump was bouncing around a lot and she wanted to disconnect. Of course she was running high that night, nearly 300 when we'd left the house to come to practice. I did some quick mental D-math (high + just bolused + no pump + constant movement = should be OK?) and we disconnected her.
It worked out great. She was back in a normal range when we got home, and she felt fine. Later that evening she went low, as she is prone to do about two hours after a lot of physical activity. We caught the low, treated, and moved on.
Now I just have to figure out how many extra carbs she'll need on the nights when she's not starting out high....
