My dd went through the same thing at 3 months... It didn't last long, I think it was as she got more efficient at feeding and would get a bit frustrated, maybe at the fact the milk wasn't coming out fast enough... It was also at 3 months when I couldn't express milk anymore, as your milk supply stream lines to pretty much what baby needs.. Not as excessive as it from birth - I am still bfing today. Just keep going it should come right :)
