My newborn is a week today and I have been managing to breast fed . Since my milk came in she has been extremely gassy and her stomach is constantly churning , she gets very upset over what I presume is a gassy stomach and trapped wind, and often is sick a while after a feed . Last night she spent it screaming if I tried to put her down , and would only settle on the breast . Over the last 12 hours she has three had really watery , yellow poos . Is this normal ?
