We're having gas attacks ??? The baby won't poop until he wakes up, only screams through his sleep. Wakes up but I squeeze his legs and he poops, and happy as anyone can be. I give him massages through his sleep, it doesn't work, gave him Eспумизан like it helped but haven't been taking it for ages, it doesn't bother his stomach anymore. What else do you suggest?
