Can breast milk sour in the breast?
Consequently, can breast milk sour inside the breast?
Sure, but not breast milk. If your body is producing milk, there is no way for it to spoil in the breast, according to the New Jersey Department of Health. This is because it is not a stagnant product of your body. It's not as though you make it, and then it sits in the breast until it is pumped or your baby eats.
Thereof, why is my breast milk sour?
Some moms notice that after defrosting, their milk smells unpleasant – soapy or even sour. This is normal! Breast milk contains lipase, an enzyme that is normally present in human milk and has a lot of benefits. Milk that has a high level of lipase can develop a soapy smell and taste, but is not harmful to the baby.
Once breastfeeding stops, your milk making cells will gradually shrink and fat cells will get laid down again. As this process occurs, over several months, your breasts usually return to their pre-pregnancy size. And, if you worried about saggy breasts, don't be.
