Does anyone else have a baby who wakes up or cannot fall asleep due to gas?  It happens at night after about 4-6 hours of sleep. Sometimes he poops and is relieved, but other times he strains and grunts for hours. Eventually he exhausts himself and falls asleep but wakes up from gas pains again. I feel like I have tried everything: bath before bed, massage, gas drops, gripe water, colic calm, bicycle legs. Does anyone else have this problem or any suggestions?
