Finn has always prefered feeding on my left hand side but for the last few days is really playing up when I try to feed him on my right hand side, its now got to the point that he has a couple of sucks and then a full blown tantrum when I put him on my right. There is milk coming out fine, I really don't want to express always on that side... any advice on how I can get him to feed again from there. I've never had any problems feeding him until now. Help!
