How were you able to tell if your baby is colicky? I'm a first time mom and its frustrating to see my baby just 3 weeks old stiffen his body and make hurt faces and then throw up. It doesn't happen every feeding but it is concerning. Sometimes he drinks too fast and most feedings I hear him clearing his throat between sucks but I'm not sure what to make of it. I told myself it's the way I hold him when I feed him or that I don't get all his burps out but I don't wanna limit my baby to my faults if there is somthing wrong. Any advice ?
