Someone mentioned the enzyme stuff. It's a lifesaver! My stinker of an exhusband helped develop one of them so we were always testing them out in our house before they came out on the market fully. They are nothing short of awesome!!! One we tested took a 5 year old red wine stain out of my carpet. Later on, I bought stuff called OUT!!! Got blood stains out of a pillow case. This is the same stuff I used when I had my kitten rehabilitation gig (as adorable as it sounds) and it worked miracles on stains and smells. And there was the time that my Labrador Retriever ate as much horse manure as he'd rolled in and then threw it up on the carpet. It was one of those 'maybe it's just easier to move' scenarios, but the cleaner worked (with some effort and multiple doses). I'm not entirely sure if that particular brand (which was my absolute favourite) is still available, but a couple other decent ones are. One is Oxy Orange Power (I think) and another is Nature's Miracle. Also a good shot is some of that oxy-clean powder. I used the generic brand of that and it's fantastic!!!

I am so, so, so sorry that happened to you....so gross! My little brother did that as a baby. We only have to casually mention the 'chocolate pudding photo' and he'll bend to our will every time Good luck with the clean up!
