Good day! Share your advice, dear moms. My son has diarrhea (he is 6 months old). It's been two weeks now, he was hospitalized twice, they said it's bacterial infection (staphylococcus), then immediately teeth started bothering him, we tried almost all medications according to doctors' recommendations. We don't know what to do. Can anyone tell me if they had this too? The color of his stool changed recently to such ?
