You know you're a mother when the baby's playgym is in your not big enough master bathroom from the last time that you took a shower, but that was last week and you still haven't moved it because if you have to step over it every time you need to go to the bathroom doesn't that count as exercise?

You know you're a mother when instead of being aggrevated that you have to load the dishwasher you realize that you've got some serious dishwasher loading skills and you experience a small burst of pride at the number of dishes you can get to fit in.

You know you're a mother when you've realized that just stepping over the playgym isn't going to return your thighs to their prepregnant state and so you start to exercise for real and even though you only need twenty minutes of time to yourself to do this you find yourself either a) holding the baby while you use a step and justify it as resistance weight instead of an intrusion or b) exercising for ten minutes then nursing the baby for thirty minutes and then exercising for the last ten minutes and count that as fifty minutes of exercise because nursing burns calories too or c) both in the same week.
