Best Infant Probiotic – Supporting Baby’s Immune and Digestive Systems

Baby Gear

Best infant probiotic

New babies are incredibly vulnerable to their environments.

Most moms, especially new ones, are bombarded with advice about how to care for their babies: how to dress them, how to bathe them, the best diapers, bottles, toys.

What a lot of people don’t consider is their internal systems. They are very susceptible to tummy upsets, viruses, and the development of allergies.

One way to give your baby a leg up is to consider giving them probiotics. The best infant probiotic can help your baby tolerate food better, prevent him from developing allergies, build a strong immune system, and more.

The bad news

Probiotics aren’t for every baby, and we strongly urge you to discuss any supplements with your baby’s doctor first. They can, in some cases, cause constipation, diarrhea and excess gas, and some babies flat-out won’t take them due to flavor, texture, or just general fussiness.

These side-effects are generally rare, and are the exact opposite of what you’re looking for when you buy baby probiotics.

What to buy

When you go to buy a probiotic for your infant, do your research. Figure out what your baby needs.

Is he or she having digestive issues or are you looking for something preventative?

In most cases, when starting probiotics for infants, ​a gradual increase to full dosage is a good idea. If you're looking to treat a problem happening right now, then you might want to just go for the full dose to see how your baby tolerates it and if it helps.

If, however, it’s something you just want to add, then your next question needs to be about what you want.

Do you want the convenience of drops? The fine, flavorless powder that mixes well in formula or breast milk? Something that has to be refrigerated, or something you can toss in your purse or diaper bag?

You can find something that fits your baby’s needs, and your own, on this list of top-rated probiotics.

Before we take a closer look, here's a peek at your best options.

One thing to remember: always check with your baby’s doctor before giving him any new kind of supplement.

There are many short- and long-term benefits of probiotics. Helping your baby develop a healthy digestive system now can prevent problems later in life.

Probiotics are an investment in your child’s future. They can help with colic, constipation, and gassiness now, but they also reduce the chances of developing allergies later in life, and they support the immune system, preparing your baby for exposure to viruses when he eventually goes to daycare and/or school.

Read the information, talk to your doctor. And most of all, listen to your mother’s intuition. You know when your baby isn’t feeling her best.

Sometimes a small change in your baby’s gut can make all the difference. Sometimes a probiotic can be that change.​
