Formula Feeding for Babies: How to Choose the Right Formula, Bottles & Feeding Plan
If you’re formula feeding your baby, you’ve probably already realised how overwhelming it can feel.
One tin says “gentle.” Another says “comfort.” Then there’s reflux formulas, allergy formulas, goat milk, thickened feeds…and somehow you’re expected to just know what your baby needs.
The truth is - formula feeding isn’t as simple as “pick one and go.”
If your baby is unsettled, gassy, refluxy or difficult to feed, there’s usually a reason. And understanding that reason is what makes feeding feel easier.
Is Formula Feeding Supposed to Be This Hard?
Short answer: no.
But many babies struggle because:
The formula doesn’t match their digestive needs
The bottle or teat isn’t supporting their oral function
Feeding is compensating for an underlying issue (like reflux, tension or tongue tie)
This is where most parents get stuck - changing formulas over and over, hoping something works.
How to Choose the Right Formula for Your Baby
Standard Formula
Cow’s milk based
Suitable for most babies
But not always well tolerated
Partially Hydrolysed (“gentle” or “comfort”)
Proteins broken down slightly
Easier to digest for some babies
Not suitable for true allergies
Extensively Hydrolysed / Allergy Formula
Proteins broken down further
Used for suspected CMPI
Often recommended when symptoms persist
Labels can be misleading - ‘comfort’ or ‘gentle’ doesn’t always mean it’s the right fit.
Signs Your Baby Might Be Struggling With Their Formula
Frequent reflux or silent reflux
Fussiness or arching during feeds
Excessive gas or discomfort
Green, mucousy or frequent stools
Skin changes (eczema, rashes)
Feeding refusal or short feeds
These signs don’t always mean you need to change formula - but they do mean it’s worth looking deeper.
It’s Not Just the Formula - Bottles Matter Too
Many feeding challenges aren’t just about what your baby is being fed - they’re about how they’re feeding.
The shape of the teat, the flow rate and how your baby uses their tongue all play a huge role in how comfortable and effective feeding feels.
This is where I often explain it like this:
Some bottle teats are shaped like a volcano - wide at the base with a gentle slope, thats what we’re looking for!
When a teat supports this shape, the tongue can move in that natural, wave-like motion we want to see. Feeding becomes more efficient, more comfortable and much less stressful for your baby.
On the other hand, teats that have a sudden drop or less supportive shape (think of a spinner top toy) can make it harder for your baby to maintain that tongue connection. Babies may then compensate by using their lips or jaw instead, which can lead to:
Clicking during feeds
Increased air intake and wind
Frustration or pulling off the bottle
Inefficient milk transfer
This becomes even more important if your baby has:
Reflux
Feeding difficulties
Body tension
Or a suspected tongue tie
Because in these cases, feeding isn’t just about getting milk in - it’s about how your baby’s oral function is managing the feed.
Reflux, Tongue Tie & Formula Feeding - The Missing Link
This is where you sound different from everyone else:
If your baby has reflux, feeding difficulties or tension, changing formula alone won’t fix the root cause.
Feeding is influenced by:
Oral function
Gut tolerance
Nervous system regulation
This is why some babies “fail” multiple formulas.
You Don’t Need to Keep Guessing
Because this is what parents are doing:
Switching formulas
Buying different bottles
Trying everything
…with no clear plan.
