Girls, when did your babies get their stools regular? We've been a week now, still liquid, greenish-brown...but I took antibiotics after cesarean. Asked the doctor, at that point it was normal, as passing stool after meconium, change in diet, the same antibiotic... but now it's unclear how it should be...Thank you!
