Could my baby's milk be causing bloating or discomfort?

Why milk gets blamed

Milk is the only variable, so milk is the suspect. It's the one thing a baby takes in, it changes in brand and type, and if a mother is breastfeeding then her entire diet becomes a suspect list too.

We had a stretch where Ari was bloated and the explanation offered was the milk. It had not been the milk the week before, when she was fine on the same milk. That inconsistency is what made us start asking for the reasoning rather than the conclusion.

Air, mostly, and a gut still learning its job.

A baby who drinks fast swallows air. A baby born early has a digestive system that is doing the work of a term baby's before it is quite ready — and ours was pushed on volume faster than she was comfortable with at one point. The result looked dramatic and was not an allergy.

Bloating, allergy and intolerance

Worth knowing, because the words get used interchangeably and they point to very different situations.

A true allergic reaction to cow's milk protein is an immune response. The urgent version is fast and obvious — swelling, hives, breathing trouble — and belongs in the red column above. The slower version shows up over days and weeks, often with eczema, blood or mucus in the stools, poor weight gain, and persistent distress.

Change one thing at a time

Ari spent a period on a hypoallergenic milk, in small amounts, with breast milk reintroduced gradually afterwards. That was done by a hospital with a plan, and the plan was the important part.

These milks are not simply a gentler formula to try at random. Ari's hospital used one as part of a clear plan, including how breast milk would be reintroduced and how they would judge the result.

There was a point where the explanation did not match what we could see. Ari was gaining weight, feeding well and passing stool, but her tummy was hard and bloated. The NICU doctors explained that they were checking for a blockage and watching how it settled. We were told she had been fed too much too soon and her tummy had become inflamed. A few days later, it softened again.

What worked was writing the questions down in advance and asking them calmly. Why are you keeping her. What specifically are you checking.

It was scary because she had been one step from coming home, then we arrived and found her back in intensive care. NICU progress is not always a straight line. We learned that through stress and panic, while the NICU nurses and doctors knew how to handle the setback.
