Baby poo frequently. And give any idea.

Dear sir my baby doing poo with every feed. She take only mothers milk. Before 5 days she do 1 poo in a day but from last five day she do 11 to 12 poo a little little rainy. She is ok but make sound when poo like stomach pain. I saw dr and dr give septran Suspension and a lactos powder. I m worried that every think is ok or not because i think more poo means dehydrration. But she is ok. What is going on dr why she make sound like pain and why do frequent poo. With every feed she sound ummha ummha and make preasure and poo. Dr check his stool test and that is ok. Dr says its some infection. And give medicine septran Suspension and lactos powder. But still the problem is same. What to do now. Is that ok if she do 11 to 12 poo. But active. Whats wrong please suggest and give any idea...
