i had very full breasts aswell if it had been a couple of hours (especially in one) the LC advised me to hand express just a little bit (30mls or so) so that my boob was a lot softer, therefore easier for bub to attach.
other than that, it sounds like you're doing a great job!!
dont worry about how many poos ur getting, lotsa wet nappies is great! bf babies can go 10 days or more without pooing!!
