Hello everyone. Such a delicate question. Son, almost three weeks, often cries out, very loudly. Yes, it could be colic, I give drops. Take him in my arms, he cries. As soon as his mother-in-law takes him in her arms, he calms down. It's been about a week like that. I understand that I don't have experience in the role of "mother", but thoughts appear that I'm doing something wrong. What can you suggest?
