Good day everyone! It's our first month. The girls have been throwing up profusely since morning after feeding, three times already today. We haven't experienced this before, we hear gurgling in their bellies and vomiting is accompanied by retching, they aren't eating anything, and their breasts also take a little bit, what could it be? We're scheduled for an appointment with a pediatrician tomorrow.
