I have nothing to add re the poo, but I know where you're coming from regarding the cracked nipples. Mine were just awful by the time I got home - no-one had looked in hospital, but they break down so quickly! (And why do they call them 'cracked'? Mine were just one big open ulcer on each side. Ulcerated nipples. Urghhh!) Normally they heal up quite quickly, too, but only if you're doing all the right things for them.

So get those nipples seen to by an LC asap. You must get your attachment checked, the sooner the better, and you may well benefit from laser treatment from a physio. Hydrogel pads were very helpful and soothing for me, too. Take deep breaths and breathe out slowly and fully as bub attaches (to help you cope with the pain, just like you might have done in labour.)
