Before Andy’s transplant and during transplant there was a direct relationship between happiness and the appearance of faeces. 

Strange.. but that’s the way it is.  Extreme parenthood…

I remember the day when I changed Andy 34 times in 24 hours. one diaper every 42 minutes. According to the chart below If he had a Type 7 it meant that we had to run to the ER due to the risk of infection given his primary immune deficiency, he ended up with  IV nutrition (TPN), IV antibiotics and antivirals for weeks..

Andy had a Type IV today.

There is hope.

The Bristol Stool Form Scale or Bristol Stool Chart is a classification of the form, that is appearance in a toilet, of faeces into seven groups. It was developed by Dr. K. W. Heaton at the University of Bristol and was first published in the British Medical Journal in 1990. The form of the stool depends on the time it spends in the colon.
