Girls, hello ❤️ Can you please tell me how to properly wean a baby? The little one is already falling asleep on her own without me and refuses to breastfeed ? How do I finish it correctly? Should I express if my breasts hurt? If not, should I not express, will it go away by itself? After how long? How to do it right so that the chest doesn't suffer too much! ? And another question, does the chest get swollen after weaning? ?
