Girls, who gave their child Duflaks? My little one can't poop without a tube, even though the stool is liquid. The doctor prescribed 1 mg twice a day, we've been taking it for a week now, no changes. The instructions say up to 5 mg. Who did how much? Maybe the dose is small or didn't help at all, I don't want to just feed him medicine like that. To the doctor, I can only get there in two weeks.
