Hello everyone. Girls, could you please tell me... We introduced baby food, and our daughter has been having trouble pooping for a week now. At first she didn't poop for two days at all, then she pooped with tears in her eyes, and now she's been going three days without pooping again. What can I give her? How can I help? I'm giving her mashed cabbage, blackberries in puree, but what else can I do to help the little one? By behavior, it hasn't changed, just when she starts pooping, she cries.
