My baby is 18 days old. She was born at 36 weeks through normal delivery and her birth weight was 2 kgs. I couldn't breastfeed her for 7 days because I had no milk supply. We formula fed her through bottle. Now I'm trying to breastfeed her but she rejects breast and is very cranky. She keeps crying everytime I try to breastfeed her. I express my milk in bottle and feed her. Please provide me with a solution for exclusive breastfeeding.
