Girls, hello, my son is 1.5 months old. He often has tummy pain, he poops very much and his tummy rumbles strongly. Especially in the evening, there are tantrums. We give him dill water, beans, massages, we wear a belt. But it doesn't really help. How can I ease the child's pain or what should I do?
