K.R.
my boys went through the same thing a month or two ago. They had very frequent very disgusting diapers for about 6 days. during that time i had to clean up 3 or 4 massive diaper blow outs. we had two in our carseats and one in bed. It just went away on its own though. it was right after our family all had the stomach flu so i figured they were still working that out.
hopefully you're almost through it!
