I'm 43 and just had my first baby 10 weeks ago. I'm stilling having some issues with pee leakage, but it's improving. At first I was just leaking at the mere site of the restroom, now I only leak after a run or elliptical work. I've gone from wearing gross huge pads that I would change every hour, to super thin max pads which I only change after a workout.

A few things that I believe are helping:

(1) I wasn't too rigorous with kegels at first. Now I do them frequently throughout the day, every day.
(2) My OB prescribed a vaginal estrogen cream. It's a low dose so it doesn't interfere with breast milk production.
(3) I have an epi-no trainer, which strengthens the pelvic floor muscles.

The best thing about the epi-no is that you can measure your results (if you buy the deluxe model with the gauge that shows how much force your pelvic floor muscles are exerting). That's important because you can improve your strength as you try to beat your last measurement. Kegels alone are difficult to measure unless you test yourself by trying to stop your urine flow from time to time to see how well you can hold it.

At any rate, make sure your OB checks you out. Urinary incontinence can be caused by a few reasons after childbirth, such as a prolapsed bladder or nerve damage in the urethra. It's good to know what you're really trying to fix.
