This fullness occurs usually two to three days after giving birth, but as many as 25% of mothers it takes longer than three days. Signs that your milk is coming in: Breast fullness, swelling, heaviness, warmth, engorgement, or tingling. Leaking milk.
Signs your baby is getting enough milk
You can hear and see your baby swallowing. Your baby's cheeks stay rounded, not hollow, during sucking. They seem calm and relaxed during feeds. Your baby comes off the breast on their own at the end of feeds.
The outer breast consists of a nipple and areola. The tip of the nipple contains several hole openings allowing for milk to flow through during lactation. The areola is the pigmented area around the nipple. It is covered with Montgomery glands that secrete oil to lubricate the nipple and areola.
Leaking colostrum is normal and some people notice it as early as the second trimester. Some don't notice any signs of leaking colostrum while others will see dried colostrum on their nipples.
Milk production generally begins around the midpoint of pregnancy, somewhere between weeks 16 and 22. At this stage your body is producing what's known as colostrum—a yellowish milk that's rich in calories and disease-fighting antibodies—which will serve as baby's first food after birth.
Some women leak a few drops of colostrum as early as the second trimester, but it's more common during the final weeks of pregnancy, if at all. If you do leak, you may notice small yellow or orange dots on the inside of your bra cups.
If you're breast-feeding, ducts carry milk from the alveoli toward the dark area of skin in the center of the breast (areola). From the areola, the ducts join together into larger ducts ending at the nipple.
“[Areolas] contain small, sensitive bumps called Montgomery's glands, which secrete a fluid that keeps the nipples lubricated,” explains Dr. Aliabadi. So bumps are kinda part of the anatomy. Note that these oil glands can also become blocked, which may make them look larger or similar to a pimple.
Montgomery Glands
They are a type of sebaceous gland (oil-producing gland). During pregnancy, the glands may become more numerous and prominent. Sometimes, they will become clogged and start to resemble a pimple. This can also occur at other times when hormone levels are changing.
Colostrum is noticeably different from breast milk. It is thick, creamy, and typically gold/yellowish in color (but it can be clear). One thing you may notice is that you will produce far less colostrum than you will transitional or mature milk.
Many newborns nurse about 10 to 15 minutes on each side, but they may take much longer. A range is normal. Older babies may take five to 10 minutes or less on each side, but again – it varies. Be sure to alternate breasts so that they get roughly the same amount of nursing time.
Your body will almost always create milk for your baby even if you under-eat. But, the nutritional quality of the milk will be decreased. Your body puts baby first, so if you aren't consuming nutritionally dense foods, and enough of them, YOU will suffer the most.
Sometimes a mother has a health condition that may temporarily delay the large increase in milk production usually seen between 3 to 5 days following birth. These mothers may not begin to produce large amounts of milk until 7 to 14 days after giving birth. If this happens to you, don't feel discouraged.
Each time baby begins to nurse the nerves in your breast send signals that release the milk in your milk ducts. This let down reflex usually happens after your baby has been sucking the breast for about two minutes. Some women feel this let-down reflex as a tingling or a warmth.
Generally speaking, breastfeeding your husband or partner is OK. It's not perverted or wrong if you want the person you are intimate with to breastfeed, or if they ask to try breastfeeding or taste your breast milk.
These bumps are called Montgomery glands. They secrete oil that helps to lubricate the areola. They become slightly larger and slightly red/pink when you are pregnant and breastfeeding.
The nipples and the area around the nipples (areola) become darker and larger. Small bumps may appear on the areola. These bumps will go away after you have your baby. You may notice a yellowish discharge, called colostrum, from your nipples as early as the 16th to 19th week.
Remember, you can always hand express if you need relief and you can't nurse or pump for whatever reason. Most importantly, remember, clogged milk duct popping is not a thing that can be done, since a milk duct is inside the breast, and popping a milk bleb or blister can lead to infection.
A plugged duct feels like a tender lump in the breast. Some mothers seem to be more prone to developing them. Usually they happen when a mother goes too long without emptying her breasts. Or, if insufficient milk is removed during feedings.
When the duct isn't draining properly (or often enough) during nursing or pumping, the milk ducts can become clogged. The pressure that builds up behind the clog causes the tissue to inflame, and it feels like a (tender and painful) small marble has lodged its way right into your breast!
Risks to mother and baby
By stimulating their nipples and expressing milk while pregnancy, women could bring on regular contractions of the womb and give birth early. This is because nipple stimulation leads to an increase in the hormone oxytocin, which plays a role in both milk let-down and contraction of the womb.
Colostrum is very concentrated. At birth, your baby's stomach is about the size of a marble, so they will only need a small amount of colostrum to receive all the nutrients they need. You can collect and freeze your colostrum during the last few weeks of your pregnancy. This has many benefits for you and your baby.
