Can anyone tell me how to Go about this please? My LO is 3 weeks and I have made the decision to transition to formula instead of breast milk. She doesn't seem to be extracting the milk efficiently from my breast despite her latch being good and no tongue tie. I have tried exclusively pumping but it is extremely time consuming with 2 kids. I'm going to go and buy some formula today but how do I got about drying up my milk without any pain/infections?
