Benefits of Breastfeeding

Breastfeeding provides a lot of benefits to both you and your baby. Most doctors recognize that babies who are breastfed get sick less than those who are fed with formula.

These babies are also less likely to get chronic sicknesses like celiac disease and childhood diabetes. Breastfeeding is also known to support stronger bones in babies.

We all know that having a sick baby in the house is hard for everyone, especially the mom.

Breastfeeding is also very beneficial to you, as a breastfeeding mom.

Has anyone ever told you that nursing your baby can burn up to 500 extra calories per day? That alone is a huge incentive to nurse your baby.

You can eat way more calories without gaining weight. Healing after delivery can be a long and difficult process, but breastfeeding your baby makes it an easier one.

Your body releases oxytocin when your baby is nursing. This hormone helps reduce blood loss after delivery by causing your uterus to contract.

It also helps your uterus get back to its normal size quickly, helping your body get back to its pre-pregnancy shape faster.

Here are some more benefits of breastfeeding

For Baby

  • Reduced cancer risk
  • Reduced SIDS risk
  • Heightened immune system
  • Customized diet that changes according to baby’s needs
  • Better response to vaccines

For Mom

  • Feeling of empowerment
  • Periods return slower
  • Some protection against pregnancy
  • Fewer sick days from work
  • Less expensive than formula
  • Better knowledge of baby’s cues
  • No heating formula or washing bottles

Storing Your Breast Milk

Breastfeeding is easiest when you are always with your baby and can just put them on your breast, but let’s be realistic.

Most moms have to go back to work when their baby is a few months old. Even if you don’t have to work, there will be times that you won’t be with your baby when they are hungry.

That’s why you need to know how to store and reheat your breast milk.

After you have expressed milk from your breast, it can be stored at room temperature for up to 8 hours.

This is the easiest way to store milk from your breast because you probably won’t have to reheat it.

The milk can also be stored for up to 5 days in the refrigerator and up to a year in the freezer.

There are several ways you can store your breast milk without contaminating it.

Glass containers are one way, but most moms don’t like having to wash the containers when they are finished. Hard plastic containers of many sizes may also be used.

Most moms have found that storage bags are the easiest and most convenient way to store breast milk, and purchasing the cheapest breast milk storage bags means that you won’t have to pay a lot of money for the convenience of using the bags.

Feeding Your Baby Using Breast Milk Stored in Bags

Learning how to store breast milk can seem complicated at first, especially if you are a new mom that is trying to learn many things at the same time.

There are a few things that you should know.

  1. Breast milk sometimes separates in the freezer. The separation is normal, and you can shake the bag gently so the fat mixes back in before feeding it to your baby.
  2. The color of the milk usually changes, depending on what you have eaten. It may look yellow, blue, brown or green. Try not to worry about the color, all of the milk is good for your baby.
  3. Putting bags of frozen milk in the fridge the night before you’re going to use them is the best way to thaw them, but you can run the bag under warm water if you need to use it sooner. Don’t put the bag in the microwave because the heat is uneven and hot spots can hurt your baby. Some babies like the milk cold, so you can try feeding your baby cold milk and save yourself the trouble of heating it up.

How Much Milk to Leave for Your Baby

Predicting exactly how much your baby will eat may seem impossible, but there are some guidelines to help you plan the amount of milk to leave for your baby when you won’t be there to breastfeed them.

Between birth and two months, most babies eat between two and five ounces of breast milk each time you feed them.

The exact amount depends on your baby. Between two months old and four months old your baby will probably eat between four and six ounces at each feeding and they may take up to eight ounces at a time when they are six months old.

Eight ounces probably seems like a lot of milk for one small baby to eat, but they grow so quickly that they need to eat a lot to get enough nutrition in their tiny bodies.

The breast milk storage bags are marked on the sides so it’s easy for you to tell how much milk is in each bag, even when you haven’t been getting very much sleep.

Breastfeeding is often overwhelming, especially at first. Reading reviews will help you choose the right system for storing your breast milk, but in the end, you need to do what works for you and your baby, regardless of what anyone else thinks.
