Hello everyone I have such a question, my daughter is 3 months old, but since the second month she has not been taking the breast at all, or rather, she hasn't taken it and accordingly the milk has gone. Now she started taking it, but there is no milk left. Is it possible to restore it somehow? The monthly ones have come recently. Has anyone had this too?
