Hello everyone, it's been two months and five days. The baby hasn't pooped in five days. Before that, he pooped for 2-3 days once. We gave him Duphalac every day, then stopped and started giving it again, but he only went once after two days and three days. What can I do? I've tried everything, including massaging his belly. He poops, but there's no poop. When he does poop, it's really thick. Can you please tell me what I can do?
