Joh - we had known about the fore and hind milk, but it seemed strange that the same thing in two babies from this mum - specialyl as they are much different feeders. We were pretty confident that her last baby probably wasn't getting the hindmilk, so she spent alot of time pumping etc, but this baby is a little piglet and is growing really well - plus spending heaps of time on the breast.
I'm putting my money on something genetic - like an excess iron thing or something like that in my friends case. This poo was bright, bright, bright green!
