According to Mrs Chee, the renowned lactation consultant, once you stopped breastfeeding, your breasts will become flatter in the short run since the fat inside your breasts was reduced for the development of 乳腺 for milk production. So, once you stopped breastfeeding, the 乳腺 will not produce milk and your breasts doesn't have the amount of fat same as before you're pregnant and so your breasts will look smaller. Mrs Chee said the breasts will resume to the normal size in the long run since it takes time for the fat to "re-establish" in your breasts. No worry!
