I have worked nights the past few years and so I have noticed my daughter getting up to go at night too. I'm not sure if she has always done this. I even had the doctor run a UA but it came back neg. So it probably is the meds. When she was a baby (she's 17 now) her diaper would be saturated compared to the other babies. (I babysat for 4 years after she was born). I know some people do this anyway but I am curious to hear from others with cah.
