My DS is 11 weeks and he has sometimes been bringing up a creamy coloured sick which has browny bits in it after a feed. I'm not sure how normal this is and whether I should be worried (I am!). He is breastfed with one bottle of Aptimil a day. He brings up milk quite a bit after a feed- could it just be irritating his stomach as it's coming up? He brought up blood two weeks ago and the hospital said it was probably a burst blood vessel and nothing to worry about. I'll call my health visitor on Monday, but any advice in the mean time appreciated.
