Girls, hello everyone We're 4 months and 11 days pregnant The baby has been pooping for 4 days now They said to give Fertal and Regidron I've been giving it for two days now, still some diarrhea, but not as much, anyway, he still poops What should I do? Can you tell me something? They say there might be something in the gums, he's active, I guess when the belly turns, he gets upset, there's fever and so on, nothing at all I'm worried
