Why Babies Scream Twenty Minutes After a Bottle

The bottle goes in fine.

That is what makes it so maddening. He is calm. He is hungry. He takes the whole thing, eyes half closed, one hand on the bottle like he owns it.

Then, twenty minutes later, the scream. Knees up to his chest. Tummy hard as a drum. And whoever is holding him is back in the hallway.

I am sixty-two. I do the seven o’clock bottle at my daughter’s house four nights a week so that she can eat her own dinner sitting down, with both hands, like a person. That was the deal. It is a good deal. The bottle is the easy part.

It is the twenty minutes after that I would have paid anything to understand.

What we tried

We burped him. Of course we burped him. Over the shoulder, sitting up, across the knee. Sometimes a burp came and he screamed anyway.

We slowed the bottle down. The slow-flow teat. The pauses. The bottle at an angle, the bottle upright, the bottle held at the exact tilt from a video.

There were drops. One kind went in the bottle, one kind went on the tongue. A mother online wrote a line I could have written myself: “Gas drops always made my girl spit up.” Ours too.

There were the bicycle legs, which work while you are doing them and stop working when you stop, and you cannot do them for forty minutes with a screaming baby on a changing mat.

There was the list. Another mother posted hers and I read it twice because it was ours: “We now burp after every 2 ounces during feeds. Tummy time included. Gripe water. Belly massages, bicycle legs. You name it, we’ve done it. Feeling defeated.”

Feeling defeated. Over a bottle. Over the easy part.

The night I sat in the car

It was a Wednesday. My daughter had eaten exactly four mouthfuls of a dinner I had cooked before the scream started. She got up. I said sit down, he is mine, eat.

I walked him for an hour and ten minutes. When he finally went down I went out and sat in my car in her driveway with the engine off, because I did not want to cry in her kitchen.

Then I did what I always do when I am beaten, which is read. Not the forums. The paediatric people.

The knot

Here is what the American Academy of Pediatrics says on its own page for parents, and I am going to quote it because I could not have said it better.

“Young babies naturally fuss and get cranky when they swallow air during feedings. Although this occurs in both breastfed and bottle-fed infants, it’s seen more often with the bottle.”

I knew babies swallowed air. Everyone knows that. Here is the sentence I had never read.

“Continued fussing will cause your baby to swallow even more air, which only increases discomfort and may make them spit up.”

Read that again, because it is a loop. He swallows a little air with the milk. It sits. It starts to bother him. He fusses. Fussing swallows more air. More air bothers him more. By minute twenty the loop has wound itself into a knot, and now he is screaming with a tummy full of something he did not drink.

The air you get back up as a burp is the easy air. The air you do not get back up goes down. And down is a gut that is a few weeks old and still learning what to do with anything.

I started calling it the after-bottle knot, because that is what it is. Not a bad bottle. A knot that ties itself in the twenty minutes after a good one.

Once I saw the knot, every failure made sense.

The burp was right, and it is still the first thing we do. The same page says to burp a bottle-fed baby “after every 2 to 3 ounces.” We do. But the burp only gets the air that is still up top. It does nothing for the knot.

The drops go in. One more thing to swallow, into a tummy that is upset about swallowing.

The bicycle legs help while they are happening. They need two adult hands and a flat baby, and they stop when you stop.

The slow teat is right too. It puts less air in. It does not undo what already went down.

What we added

I want to be careful here, because I am not going to tell you a thing on a baby’s tummy stops him swallowing air. Nothing does. He is a baby with a bottle.

What I wanted was something for the knot. Something that stayed warm and gently snug across his tummy for the twenty minutes after the bottle, while the air worked itself through, without my hands, so that I could hold him upright and my daughter could finish her dinner.

A mother online had already worked it out before I did. “We place it 5 mins before feeding and during feeding.”

It is a small soft band that goes around his middle. A warm insert you heat for half a minute. Mild warmth and an even, gentle snugness across the belly. Not tight. Snug, the way your forearm is snug when you hold him against you. Except it stays, and it does not need an arm.

What actually happened

The first night I put it on before the seven o’clock bottle, the way that mother said. He fed the same. I burped him the same.

Minute twenty came. He squirmed, he grumbled, he brought his knees up once. Then he put them down again. No scream. My daughter looked at me across the table with her fork in the air.

Some nights there is still a scream. Some nights the burp does not come and he is cross about it, band or no band. He is a baby. I would not believe anyone who told you otherwise.

But the knot does not tie itself the way it used to, and dinner in that house is a meal again.

One warning, since you will search anyway. There are bargain lookalikes about, and with babies the cheap one is the one you buy twice, and it comes with no promise behind it. This is the one with the guarantee. It is forty-five dollars, or three for ninety. One on the baby. One in the wash. One at Grandma’s house.

One plain line, because I am somebody’s mother first

A baby who screams after every feed and also arches, vomits with force, refuses the bottle, or is not gaining weight is not a knot problem. That is a call to your paediatrician this week, not a thing to wrap. Ask them. I am a grandmother with a story, not a nurse.

I still do the seven o’clock bottle. I still burp him at every two ounces, because the people who know say so and they are right.

I just stopped dreading minute twenty.
