I had mastitis when both my DC were v young and am worried I have it now - DS is 14months though. Is it unusual to have mastitis at this stage of feeding? I have been quite tired and run down (both DC are terrible sleepers) and lost my voice last week - could this be related? One v sore boob (although no obvious red patch), achy, shivery and nauseous. Still the sore throat although don't know if this is related.... Does it sound like mastitis? And what should I do? When the DC were small I fed frequently to clear blockage but now DS just has a morning feed, a 4pm feed, a 7pm bedtime feed. Would it make things worse to encourage him to go on that side more often?
