Hello everyone?Has anyone encountered this? We've been gradually introducing mashed vegetables and rice porridge for six months now. But our stool is still watery. The pediatrician says we need to dilute rice porridge with lactose-free formula and give her without milk cereal. I thought about sending the stool for analysis but she says it's not necessary. But I'm scared of the mucus in the stool, though the mucus has always been present since birth. I thought that after weaning the stool would be thicker but no.
