Baby poop

Katie

So we were going every day 6-8 times, it was the yellow/brown color and for he last few days she’s only gone once a day and it’s thick and black. We go to the doctor tomorrow. But idk if something is wrong, where she’s mostly breast fed, or because she’s taking a multivitamin. Or because I’m taking my prenatal and she’s on a vitamin. Idk if I can give her anything
