If you’ve added lactation cookies to your routine to support milk supply, but your baby seems more gassy, unsettled or uncomfortable, you’re not imagining things — and you’re definitely not alone.

Many mums reach for lactation cookies because they’re convenient and widely recommended. But for some babies, certain ingredients commonly found in these products may contribute to wind, tummy discomfort or increased fussiness.

Let’s gently unpack why this can happen, what ingredients may be contributing, and how to support your baby’s digestion if this sounds familiar.

Why Your Baby’s Tummy Can React to What You Eat

When you’re breastfeeding, small amounts of what you consume can pass through your breast milk. While this is completely normal, some babies have more sensitive digestive systems, especially in the early weeks.

This doesn’t mean you’ve done anything wrong. It simply means your baby’s gut is still developing and learning how to process new inputs.

Common Ingredients in Lactation Cookies That May Cause Tummy Upset

Not all lactation cookies are the same, but many contain ingredients that can be harder on sensitive tummies.

1. Dairy (Milk, Butter, Whey)

Dairy is one of the most common sensitivities for breastfed babies. In some cases, proteins from cow’s milk can contribute to:

• Wind and gas

• Fussiness after feeds

• Discomfort during digestion

This doesn’t mean all babies react, but for some, even small amounts can make a noticeable difference.

2. Wheat and Gluten

Wheat-based cookies can be heavy and harder to digest for some mums, which can indirectly affect baby. In sensitive cases, wheat may contribute to:

• Increased gas

• Digestive discomfort

• Changes in stool patterns

Again, not a problem for everyone, but worth considering if symptoms appeared after introducing cookies.

3. Soy

Soy is another common ingredient in processed foods and baked goods. It can be difficult for some babies to tolerate and may contribute to:

• Wind

• Fussiness

• Unsettled feeds

4. Added Sugars and Sweeteners

Many lactation cookies are high in sugar or contain sweeteners to improve taste. High sugar intake can affect digestion and, for some babies, may be linked to:

• Increased gas

• Restlessness

• Evening fussiness

Sugar can also leave mums feeling sluggish rather than nourished.

5. Highly Processed Ingredients

Some lactation products include highly processed ingredients. While these are often added for taste, they may not agree with every mum or baby and can contribute to digestive changes.

Signs Your Baby May Be Reacting

Some common signs mums notice include:

• Increased wind or gas

• Pulling legs up after feeds

• Fussiness or crying shortly after feeding

• Unsettled sleep

• A baby who seems uncomfortable despite feeding well

If these symptoms started after introducing lactation cookies, it may be worth reassessing.

What Can Help If You Suspect a Reaction

The first step is always gentle observation. Some mums choose to:

• Pause the cookies for a few days

• Notice any changes in baby’s comfort

• Focus on hydration and simpler/cleaner support

If symptoms improve, it can be a helpful clue.

Supporting Baby’s Digestion Gently Through Breastfeeding

For mums looking for a gentler option, digestive-supporting herbal teas can be a soothing alternative.

Colic Tea works through the mother’s milk, using gentle, traditionally used herbs to help support digestion and ease wind. Rather than adding anything directly to baby, it supports comfort naturally and calmly. Alternatively our Lactation Tea is kind on tummies, organic and free from dairy, gluten, sugar or processed ingredients.

Many mums choose this option when:

• Their baby seems gassy or unsettled

• They want to avoid heavy, sugary products

• They prefer a calming daily ritual

Every Baby Is Different — And That’s OK

It’s important to remember that:

• Not all babies react to the same foods

• What works for one mum may not work for another

• Your breastfeeding journey doesn’t need to look like anyone else’s

If symptoms persist, it’s always wise to check in with your GP, lactation consultant or trusted healthcare provider to rule out other causes such as attachment issues or sensitivities.

A Gentler Way Forward

If you’re feeling unsure, overwhelmed or guilty, please know this — you are doing an amazing job.

Sometimes, small changes can make a big difference. Choosing gentle, nourishing support that works with your body and your baby’s developing digestion can help bring calm back into feeding time.

You deserve support that feels good for both of you.

If you’re looking for a gentle way to support baby’s digestion through breastfeeding, Colic Tea may be worth exploring.
