Belfie that is so friggin awesome! You are the best!
I know exactly how hard it is in those first few weeks - really hard. As for the positioning - the most important part is that he gets on and gets enough milk. I could never hold my baby like the midwives said as I too have big boobs and bubs was very long. I bf for 11 months, I always held my boob and he always lay on a pillow. Keep your eye on the ultimate aim - him getting fed - and dont get too hung up on what other people (especially non LCs) say you 'should' do. If it works for you then you should do it. One day you will just realise that the whole thing is easier and from then on it is a breeze.
Good job!
