My 3 months baby poo three times a day and people says its teeth, how true is that?
Also note that Babies on EBF do not need to poo daily, they can stay up to 2 weeks without having to poo. Sometimes, they can even poo up to 12 times in a day. As long as the stools are normal. There's nothing to worry about.
Teething doesn't cause fever or diarrhea.
Is your baby on EBF?
