My dd is almost 2 months and all of a sudden her poop stinks and it didn't before. I should know this as this is my 3rd exclusively breastfed baby, but I do NOT remember this ever happening until they started eating food. There is nothing noticeably different about her poop and she doesn't seem to be uncomfortable about pooping or anything. She has slacked off with the frequency of pooping which I know it normal, maybe this is the reason. Any ideas?
