Girls, hello everyone. I apologize for the photo. The baby is three months old and started pooping like this, (green stools, yellow-green) sometimes there's still a smell. What could it be? And what do you recommend? The pediatrician recommended giving him bobetik 3 times a day and biogaju once, but nothing improves. How he eats, he immediately poops after 10-15 minutes. Cleanly on breast milk. I think maybe give him formula to normalize stool. Or is it to the teeth? Everyone says that it's in order of norm, but something is a bit worrying.
