I just can't win

I feel like I just can't win right now.  First Josie was totally miserable because she was constipated again.  So to resolve the situation, since nothing else was working, we gave her the Miralax like the doctor said.  So that solved the problem and she had a breakthrough so to speak.  Now she has multiple soft movements a day.  So much so that now she has a diaper rash!  I just can't win...
