Am breastfeeding my new DS2 and after 2 weeks of him being blissfully contended he's suddenly started coming off during feeds, whilst still seeming to want to be latched on IYSWIM, screaming as though he's really in pain and arching his back. This goes on for a while and is really frustrating as I just don't know what to do; trying to put him back on seems to make him worse, although he seems desperate to feed? He ends up almost head banging my boob and wrestling me with his hands - I vaguely remember his big brother doing something similar. Am having trouble getting his wind up and wondering if it's colic, but doesn't that start later on? Am worried in case it's something more serious, but not sure about taking him to the GP in case they say it's just wind/colic.
Anyone had this and have any idea what it is and what I can do?
