From our experience, we had to suffer what we called the double barrel. Every time we change our girl's diaper (she's currently 8 weeks old) we have around of 3 - 5 diaper changes at a time. Most of those are pee, but up until a week ago, it could be 2 - 3 poos in a row. While it might seem disgusting, we don't change the diaper immediately, instead we try to wait for all the shots to fire first. This never works, but waiting a bit does seem to cut down on the number of changes in a row. We also keep Aquaphor close at hand it's the best at combating diaper rash and it's easy to apply though a bit greasy, so keep a dry towel at hand for wiping it off of you. A good thing to note, I'm not saying it smells like roses, but if you're breastfeeding your baby's poo won't be as nasty as if you're feeding formula. I only mention it as it might make it not so disgusting if you have to change it on the floor.
