We know that becoming a parent has you in different emotions. Be it excitement, love,
and yes – a little bit of worry (well, not really a little). This worry can turn to something
catastrophic, and it can feel like you don’t have some things in control. When my first
baby showed signs of a milk protein allergy, I felt overwhelmed trying to find the right
formula. You might be feeling the same if your little one is experiencing fussiness, colic,
or skin rashes.

Now, when it comes to different hypoallergenic formulas, the Gerber Extensive HA and
Nutramigen are two of the most recommended options by many. Still, knowing which is
the best fit for your baby could take hours to do your research. So, in this blog post, let’s
break it down together!

What are Hypoallergenic Formulas for your baby?
Hypoallergenic formulas are specially designed for babies who have trouble digesting
regular cow’s milk protein. They either use extensively hydrolyzed proteins (broken into
smaller pieces) or amino acids to make digestion easier and reduce allergic reactions.
Both Gerber Extensive HA and Nutramigen fall into the extensively hydrolyzed formula
category, making them excellent choices for sensitive tummies.

What is Gerber Extensive HA?
This formula is designed for infants with cow’s milk protein allergies or some babies with
other digestive concerns. Gerber Extensive HA might work for your baby if you want:
• Hydrolyzed Protein: The proteins in this formula are broken down extensively,
making it gentle on your baby’s stomach.
• Lactose-Free: If your little one is lactose intolerant, this is a great option since
it’s completely free of lactose.
• Probiotic Benefits: Gerber Extensive HA includes Lactobacillus reuteri, a
probiotic shown to help with colic and improve digestion.

In my personal experiences, when I first tried Gerber Extensive HA for my daughter,
who had constant colic episodes, the improvement was noticeable within a week. My
husband literally couldn’t believe how quickly his fussiness subsided.

What is Nutramigen?
On the other hand, Nutramigen is a household name for hypoallergenic formulas – and
for good reason. This brand has been trusted by parents for decades to offer babies
some relief from their sever allergies. Nutramigen might work for you if you want:
• Hydrolyzed Proteins: Like Gerber Extensive HA, Nutramigen breaks down
proteins to make them more digestible.
• LGG Probiotic: This formula contains a unique probiotic that supports gut health
and helps manage cow’s milk protein allergies.

• Clinically Proven Results: Nutramigen boasts a 90% success rate in improving
allergy symptoms within 48 hours.

A close friend of mine swears by Nutramigen. Her baby had eczema and constant spit-
ups before switching to this formula. Within days, the spit-ups stopped, and the eczema

began to clear up.

Tips for transitioning to a hypoallergenic formula
Switching your baby to a hypoallergenic formula can feel like a big step, but with a little
preparation and patience, it can be a smooth process for both you and your little one.
Here are some things you need to remember when transitioning to a hypoallergenic
formula:
1. Introduce it gradually

When I transitioned my baby to a hypoallergenic formula, I still remember how
nervous I was about how he would react to the new taste.
One trick we learned from her pediatrician was to mix a small amount of the new
formula with the old one. Start with a 3:1 ratio (three parts old formula to one part
new formula) and gradually increase the amount of hypoallergenic formula over
the course of 5–7 days. This helps your baby adjust to the taste and texture
without making it feel like a drastic change.

2. Patience is key

Babies are creatures of habit (aren’t we all?), and it’s completely normal for them
to take some time to accept a new formula. The key here is not to panic if your
baby seems hesitant at first. Offer the bottle with the new formula during their
usual feeding times and stay calm if they don’t finish it right away.

3. Monitor your baby’s reactions

This is perhaps the most important step. Once you begin the transition, pay close
attention to how your baby reacts—not just to the taste, but also to how their
body responds. Are their symptoms improving? Do they seem less fussy, gassy,
or uncomfortable? Having answer to these questions will help you track
everything including bowel movements, skin changes, and even sleep patterns.

4. Embrace trial and error

Sometimes, it might take trying a couple of different hypoallergenic formulas to
find the one that suits your baby best. I’ve seen parents feel overwhelmed by this
process, but remember: every baby is unique, and what works for one might not
work for another. Of course, never hesitate to reach out to your pediatrician for
guidance.

Choosing between Gerber Extensive HA and Nutramigen can feel daunting, but
remember, you’re doing this out of love and care for your baby. Both formulas have their
strengths, and either option can provide the relief your little one needs.
