Hello everyone! Could you please tell me how to stop a baby from breastfeeding? He can't do without it. When he sucks on the breast so hard that his eyes get watery with pleasure and all day long, there is no strength left and nowhere to go, we are 1 and 2 months old ?. And it's sad to deprive the child of pleasure and I am already tired?
