My 7 week old bf baby has her first cold. She is pooing much more than normally and it is green and mucousy - I'm assuming this is related to the cold but it's been going on for five days now - should I take her to the GP? Never experienced this with DC1 but he didn't get ill this young. She drinks plenty of milk on each boob so it can't be not enough hind milk as some websites have suggested.
