Some mothers feel a tingling or pins and needles sensation in the breast. Sometimes there is a sudden feeling of fullness in the breast. While feeding on one side your other breast may start to leak milk. You may become thirsty.
When your milk comes in, your breasts will become fuller and firmer. If your baby is feeding well and frequently, this should pass without problems. However, some women's breasts become rock hard, and they may also be tender, uncomfortable, even painful – a condition called breast engorgement.
Despite views to the contrary, breasts are never truly empty. Milk is actually produced nonstop—before, during, and after feedings—so there's no need to wait between feedings for your breasts to refill.
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.
Increasing your milk supply will take time, so don't give up. Even dry pumps (when you pump but nothing comes out) sends a signal to your body that more milk is needed on tap, so it's getting the work done even if there's no output to show for it right away. Stick with it and you'll see the results after a few days.
In pregnancy, the breasts may start to produce milk weeks or months before you are due to have your baby. If your nipples are leaking, the substance is usually colostrum, which is the first milk your breasts make in preparation for feeding your baby. Leaking is normal and nothing to worry about.
To put a number on it, it usually takes about 20 to 30 minutes after feeding to generate enough milk for your baby, and about 60 minutes to replenish fully. The more often your baby feeds, and the more they empty your breasts, the more milk your body will produce.
Heat can help to stimulate milk production, which is why many nursing parents find that just coming out of a hot shower is a great time to pump. Warm compresses can also help, and can be a more portable option, if you're looking for something to take to work.
Milk production is a demand and supply process. As milk is removed from your breasts, your body is signalled to make more milk. The more frequently and thoroughly the breasts are emptied (though breasts are never truly 'emptied'), the faster they try to refill.
Some moms describe a deep ache or dull throbbing pain after they complete a feeding. This feeling can start 10-20 minutes after the feeding is over and usually lasts 10 minutes or less. The ache is from the filling up of the alveoli with blood and lymph fluid in preparation for the next feeding.
Changing hormone levels can cause changes in the milk ducts or milk glands. These changes in the ducts and glands can cause breast cysts, which can be painful and are a common cause of cyclic breast pain. Noncyclic breast pain may be caused by trauma, prior breast surgery or other factors.
If there is a continual delay in letdown from the breast it can lead to reduced milk supply. Babies are also really in tune with how their mother's are feeling. Your baby can totally sense when you are sad, stressed, or anxious.
Your breasts feel softer
This happens as your milk supply adjusts to your baby's needs. The initial breast fullness reduces in the first few weeks. At around 6 weeks, breast fullness is completely gone and your breasts may feel soft. This is completely normal and has no effect on your milk supply.
Some might feed every 90 minutes, whereas others might go 2–3 hours between feedings. Newborns should not go more than about 4 hours without feeding, even overnight.
Some mothers can store 4-5 ounces per breast, so baby would only need to eat from one at each feeding. Other moms can store 1-2 ounces and baby would need to feed from both breasts. Storage capacity is not indicated by breast size, but by glandular tissue in the breast.
Adequate hydration also is important for breast milk production. The amount of liquid you put into your body affects how much breast milk you can produce. I encourage women to carry a bottle of water for themselves in their diaper bag.
How do I know whether my breasts are empty? There's no test or way to know for sure. In general, though, if you gently shake your breasts and they feel mostly soft and you don't feel the heaviness of milk sitting in them, you're probably fine.
You can increase your milk supply by: Nursing your baby often. Nurse every 2 hours during the day and every 3 to 4 hours at night (at least 8 to 16 times in 24 hours). If your baby will not nurse, use a good quality double electric breast pump to increase milk production.
Cluster feeding doesn't mean you don't have enough milk. However, some parents are concerned that they may not be producing enough milk for their baby during cluster feeding episodes. If you are in such a situation, be sure to: Stay hydrated.
Making milk creates denser tissue in your breasts. After breastfeeding, both the fatty tissue and connective tissue in your breasts may shift. Your breasts may or may not return to their pre-breastfeeding size or shape. Some women's breasts stay large, and others shrink.
You're not getting let down. If your breasts feel like they're full but you're not able to get the milk flowing out when you pump, it could be that you're not achieving let down. The let down reflex releases your milk from the milk ducts. This only occurs when you're either breastfeeding or pumping.
If your breasts don't leak very much, you don't have to worry about wearing a bra. But, if you have very leaky breasts, you need something to hold your nursing pads in place. This will save you from waking up in a puddle of breast milk and having to change the sheets every morning.
Some women feel the let-down reflex as a tingling sensation in the breasts or a feeling of fullness, although others don't feel anything in the breast. Most women notice a change in their baby's sucking pattern as the milk begins to flow, from small, shallow sucks to stronger, slower sucks.
It happens when your breasts are particularly full of milk or when something makes your body think that breastfeeding has happened, activating your “letdown reflex”. It can also be an emotional response – some women report their breasts leaking when they hear their baby crying.
