Hoping for some sound advice here as gp not very helpful. My DD had her rotavirus vax 4 weeks ago and hasn't had a normal BM since. She goes up to 4 days (normal as she is BF) has foul smelling gas (probably normal as going days) but it's thick and foul smelling. I was washing it off her clothes today and it smells of minerals, iron even. No sign of blood. It's mustard colour but peanut buttery and she's breastfed. It's been like this since the vax. I'm thinking to give her a probiotic? She's content and thriving but something doesn't seem right here.
