My little man is 5 months old and exclusively breastfed. I've just overcame my third bout of Mastitis - all from my left boob. But now bub seems to be rejecting that side? And hardly wants to feed off the other. He has been a little unwell. I'm just concerned because his fontanelle is constantly sunken throughout the day (I should mention that he is feeding fine at night).

What's happening? What can I do? I'm just persisting but its futile and I'm getting no where.
