FTM here...my DS is 1 month old and his poop has changed color in the apst few days. It is definitely more brown now, rather than the yellow it has been (I am EBF). Is this normal? Do I need to call my doc tomorrow?? He also has a bit of a diaper rash...we switched wipes though, so I am going to go back to what I have ben using. Thanks for your advice!
