I very recently had an interesting conversation regarding multi-tasking with my middle little. I can't imagine anything else. I'm always doing 3-4-5 things at a time. If I'm not, I get fidgety and feel like something isn't getting done.
Over the years I've tried to get her to "use her time more wisely" and do some multi-tasking but it always throws her off when she tries and NOTHING gets done.
Turns out she's mildly ADD and needs to focus on one task at a time. Very difficult for me to relate because I'm the opposite, but we have fun helping each other with our disorders :)
