When does milk comes from breast?

Answer 1

The alveoli in your breasts start to develop in the first trimester, because of hormones secreted by the placenta. This is why most women notice their breasts getting fuller in early pregnancy. Milk production could be theoretically possible around the 4th month, but progesterone excreted by the placenta actually keeps the prolactin receptors away from the cells that make the milk. So it's not so much a matter of 'when does it start' as 'when does our body stop keeping it from starting'!

It's interesting to note that in animals who are born, nurse, and need to get up and run around the pasture within about ten minutes, their progesterone levels drop about four days prior to birth, so the milk is available immediately. In humans, our progesterone levels dive at birth, with the expulsion of the placenta. So four days after birth, our milk comes in. That's okay... baby doesn't need more than colostrum before then.

It's also interesting to note that sometimes, if there is any part of a retained placenta, there could be inhibition of lactation. This is pretty rare, and doctors and midwives can generally tell if there's been retained placenta.

One other thing about lactation: it's a supply-demand process. You can imagine a chef back there, cooking up the milk, and he's only going to make as much as he thinks there are customers for. So the more your baby nurses in those first few days -- even before your milk comes in -- the more milk will be available. That's why it's so important not to supplement with formula, and to nurse on demand. :) If you can get your baby skin-to-skin as much as possible in that first week, that will really enhance baby's brain development, temperature and respiratory regulation, and also your milk production, too.

Hope that helps!

When you are about 6 months, your body may start to prepare to begin milk production. Usually around 7 months, you will notice "colostrum" either leaking or expressed from the nipples. This is premilk, and for some women, it does not appear until after the birth of your baby. About 3-4 days after birth, you will feel your breasts becoming engorged. This may cause your breasts to enlarge 3-4 times there original size, and can be hard, and very painful.

Many physicians believe the breasts are not fully mature until a woman has given birth and produced milk. Breast changes are one of the earliest signs of pregnancy - a result of the pregnancy hormone, progesterone. In addition, the areolas (the dark areas of skin that surround the nipples of the breasts) begin to swell followed by the rapid swelling of the breasts themselves. Most pregnant women experience tenderness down the sides of the breasts and tingling or soreness of the nipples because of the growth of the milk duct system and the formation of the many more lobules.

By the fifth or sixth month of pregnancy, the breasts are fully capable of producing milk. As in puberty, estrogen controls the growth of the ducts and progesterone controls the growth of the glandular buds. Many other hormones, such as follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin, oxytocin, and human placental lactogen (HPL) also play vital roles in milk production.

Other physical changes, such as the prominence of the blood vessels in the breast and the enlargement and darkening of the areola occur. All of these changes are in preparation for breastfeeding the baby after birth.

When I was pregnant my "milk" came around 6 or 7 months... I didn't even notice it until it was leaking all the way down my shirt and all over the front of me... highly embarassing but that WAS my first pregnancy... so now that I know... next time I will be wearing those "pads" as soon as I hit 6 months or so... just in case lol...

Most Commonly, Breast milk is first produced after the birth of a baby. But it may also be produced following the process or Induced Lactation, or Relactation. In either case, overall it is caused by sudden increases in lactation related hormones which trigger the breast to produce milk.

Answer 5

Milk forms in the breast of a mother when the baby is 1 to 3 days old. Most women will experience their breasts feeling very full (even uncomfortable) at this stage. This is perfectly normal and is known as engorgement and will pass. Mothers who choose to breastfeed will notice that their milk gradually changes to a creamy colour.
