So I’ve been taking milk flow supplements with fenugreek in them. I’ve noticed a change in my babies stool I’m only taking 1-2 pills a day and I space them out but I’m not sure if I should continue them because of this change he isn’t constipated he poops regularly. Any moms experience any of this and what did you do? I have an appointment with his doctor on the 8th and I was going to talk to him about it then but I’m just curious on why his stool has changed in color and texture!?
