Ds is 3 weeks and after a rocky start bf had been going ok, with the odd oz of formula here and there just to take the pressure off. In the last couple of days ds often seems really unhappy feeding from the right side - thrashes around and gets in a right tizz, and when I try and express (though I can barely get anything from either side anyway) the 'jets' seem much smaller from that side, so I think milk comes out much slower.
Is it possible that I have one malfunctioning breast?
