gness...just seen you additional post......slaney has given you an answer with which I agree entirely.
Acute bowel obstruction in a 7 month old baby needs policy of "getting in, doing what is necessary and getting out" ...not the time for rooting around. The kidneys of a baby may only be half a centimetre at most and would have been impossible to see, by chance, unless you were looking.
As far as OH was concerned, a transplant from your daughter, if that is what you were thinking "may" have been an option, but in that case there would have been other variants to consider.
