Apologies for the indelicate subject and gross description, but would really appreciate some MN experience. I've a 3 month old bf baby and her poos have recently changed. Whereas several weeks ago she was pooing several times a day and it was the classic bright yellow with curdy bits in it, then she went a bit frothy and I thought she had a tummy upset. Now she's only going once a day and it's smooth and a dark mustard colour and comes out fast, like the runs. She's always suffered from colic.
Should I be worried? Is it normal for the consistency of their poos to change. I can't think I've been eating any differently.
Thanks!
