If you pumped both breasts at once and the total amount of milk will fill one bottle no more than two-thirds full, you may combine the contents in one bottle by carefully pouring the milk from one sterile container into the other. Don't combine milk from different pumping sessions when pumping for a high-risk baby.
You may combine milk pumped from both breasts into a single container. Just carefully pour the milk from 1 container into the other.
As long as the freshly pumped breastmilk is sufficiently chilled, it can be added to a bottle of milk pumped earlier that day and even to refrigerated milk from a pumping session the previous day.
You can let your baby nurse on one side and pump the other side simultaneously. Just remember to start your baby's next nursing session on the side they didn't nurse from previously as a breastfeeding baby is capable of emptying the breast more than any mechanical pump.
Many women find they produce a lot of milk in the morning. This is often a good time to start pumping. Also if the baby does not feed from both breasts, you can pump the opposite breast. You can also pick a set time each day to add in a pumping.
If you pump 4 ounces or less from both breasts in a pump session, you're able to pump on one side and keep pumping into the same milk bag or container on the other side. To do this: When you've finished pumping on the first side, press pause and break latch.
If you're pumping for a freezer stash or to store milk for a future separation from your baby, try pumping shortly after you finish nursing – maybe 15 to 30 minutes. That way, your body will have an hour and a half or so to replenish breast milk for your next nursing session. More on combining pumping and nursing here.
A full milk supply is 25 to 35 ounces per day. Once you've met this goal, you may find that you are able to reduce the number of times per day that you pump and still maintain your supply. You can drop out one pumping session every few days and keep an eye on your milk supply.
Ideally, you would pump as often as your baby would nurse. This may not be possible with your work/ school schedule. Most mothers find that pumping every 2-3 hours maintains their milk supply and does not cause them to become uncomfortably full.
One breast is not producing milk any more
Breastfeeding your baby on the basis of supply and demand (whenever your baby needs to be fed) is the key to making enough milk. If one breast is allowed to 'dry up', it will be smaller than the breast that continues to make milk.
Aim to spend 15 to 20 minutes hooked up to the pump to net a good amount of breast milk (some women will need 30 minutes or more with the pump, especially in the early days). Pump until the milk starts slowing down and your breasts feel well-drained. Be sure to clean the breast flanges after every use.
The most basic pumping position involves sitting down with your shoulders set and your back straight. Ideally, you'll want to do this in a comfortable, padded chair with armrests to help support you while holding your breast shields in place.
Ultimately, if your baby has reached its birth weight and you're pumping enough milk during the day, it's okay to sleep eight hours without pumping at night. Keep in mind there is an adjustment period for your body as it begins to acclimate to the decrease in overnight milk removal.
This question comes up often as more breastfeeding moms are pumping and often times, exclusively pumping to produce breast milk. Another common related question that moms ask is does pumping burn as many calories as nursing? The answer to this helps answer the first question, which is a resounding Yes!
Once your milk supply begins to increase from drops to ounces, you may want to pump longer than 10 minutes. Many women find that pumping for about two minutes after the last drop of milk is an effective way to stimulate more milk, however, avoid pumping for longer than 20 - 30 minutes at a time.
If your baby wants to breastfeed right after breast pumping, let them!
The decision to breastfeed during the day but give infant formula at night is a common choice for many moms. This decision to combo feed— any sort of mix of breast milk and baby formula- allows for both formula feeding and breastfeeding interchangeably. Combo feeding with a night bottle is a great solution.
Too much pumping can cause problems for nursing moms. Supply is a function of demand – the more milk that you remove, the more milk you may make. Therefore, a lot of extra pumping in addition to nursing could lead a nursing mom to have an oversupply.
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.
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.
Try not to go longer than about six hours without pumping if baby is eating during that time. That means, don't skip more than one breastfeeding without pumping. Note: If baby is sleeping longer stretches at night, you should be sleeping those stretches, too.
Milk from different pumping sessions/days may be combined in one container – use the date of the first milk expressed. It's a little unclear what the VeryWell article means, exactly. It says it is okay to mix milk you pumped on the same day, but not different days.
You can determine your Maximum Comfort Vacuum by increasing the vacuum until pumping feels slightly uncomfortable (not painful), then decreasing the vacuum slightly. A vacuum level that is too high doesn't equal more milk; it equals more pain!
Healthy infants who breastfeed effectively are often thought to be more efficient than the expression of milk either by hand or with an electric breast pump. Breastfed infants have been shown to remove 50% of the total volume of milk removed at a breastfeed in the first 2 min and 80% in 4 min [31].
✏️ Do nothing. If your baby is naturally sleeping longer at night on their own with no sleep training, your body will naturally regulate your supply.
