Can anyone help? I'm caught in this gruelling cycle of feeding my three week old, hoisting him up on my shoulder to burp him and to try to help him keep the milk down, some of which always comes out as soon as i put him flat or not vertical. he possets all the time, then he says he's hungry again and i don't know whether to feed him all over again and start the cycle or try to soothe him. Lots of people have told me some babies simply posset more than others but this is ridiculous. It's hard to even go out because i have to keep him upright for so long after feeds. My arms and wrists are exhausted. Anyone else gone through this? He also seems in discomfort after a feed and makes a weird straining noise, almost like one an adult would make if constipated... Any tips or soothing words gratefully appreciated!
