baby probably has gas , try walking all around the house with the baby slowly bouncing up and down or sit at the edge of the bed and bounce on the bed , try taking the baby a warm bath to feel refreshed, i also heard gripe water helps never tried it myself , if the baby has bad gas problems get the Dr. Browns Natural flow bottles they help with gas spit up and reduces colic , my babygirl had gases like crazy and she would scream in pain and i changed the bottles to those and she barely has gas i burp her and they are little burps
