Girls, who have babies who spit up!? Tell me, I have a baby with reflux, he never really sputters much. Now for four weeks, and he probably eats and spits up immediately. I've been feeding him less, but he still manages to spit up and then laughs afterwards. I read that normal is up to two tablespoons. But it bothers me that this happens every time after each feeding and sometimes just when playing after feeding. Could it be that his stomach is rearranging itself, preparing for food? He's on mixed diet, could that affect it? Share your experience!
