Grunting / passing wind

sarah

Hi. My son is 7 weeks old and grunts a lot throughout the night while sleeping when he is trying to pass wind. He grunts and screeches while trying to pass wind after every feed as well. He is also throwing up quite a lot once he burps and/or has hiccups. Has anyone else experience the same thing and do you find you need to feed him more frequently since he throws everything up. Thanks, Sarah
