Teething, Ear Infection, or Regression? Telling Them Apart

Here’s the honest version, delivered at 5:50am while you’re finding somebody’s shin guards: you cannot reliably tell these three apart from your own hallway, and one of them needs a doctor. Teething and sleep regressions are things you ride out. An ear infection is a thing a clinician diagnoses — nobody can confirm or rule it out without looking in the ear, which is a sentence that includes you, me, and every search result you’re about to open. So the practical order is: watch for the signals that mean call, call if you see them, and only then start managing the sleep. Not the other way around.

Why the third night is the one that breaks the week

The pattern in a sports-season house is always the same. Night one, the baby’s up twice and everyone shrugs. Night two, up four times, and the eleven-year-old wakes at 5:30 to a house that’s already awake. Night three, somebody’s got a 6:00pm practice and there is not one functional adult in the building. Nobody’s actually asking “what’s the etiology here.” They’re asking whether this ends by Thursday, and whether they can hand the practice run to another family without explaining the whole situation in the group chat.

The catch is that the answer to “does this end by Thursday” is different for all three. So the question does matter — right after the safety question, which comes first.

What parents commonly notice with each

Not a diagnostic tool. This is what families typically report, and every one of these overlaps with the others, which is the whole problem.

Teething. Parents usually describe drool, chewing on everything within reach, sore-seeming gums, and a baby who settles fine and then wakes when they’re lying flat and the distraction of daytime is gone. It tends to come in bursts of a few rough days around a tooth, then quiet. Betteroo’s rundown of how teething and sleep actually interact is worth reading mostly because it’s honest about how much gets blamed on teeth that isn’t teeth.

A sleep regression. Parents describe a baby who was sleeping fine and abruptly isn’t, alongside something new in the daytime — rolling, crawling, pulling up, a word, a burst of separation protest. Bedtime often gets harder, naps go short, and the baby is frequently awake and cheerful at 2am rather than distressed. It’s developmental, it’s not an illness, and it passes on its own schedule.

An ear infection. This is the one families ask about most and the one this post won’t try to settle. Parents commonly notice ear pulling or tugging, a baby who cries harder when laid flat, fussiness that’s out of proportion to everything else, a fever, fluid or drainage from the ear, or a rough patch arriving in the tail of a cold. Every one of those items also appears in the teething paragraph or the regression paragraph, or both — which is exactly why the resolution to this question is a phone call, not a checklist. The American Academy of Pediatrics keeps a parent page on ear infections in children; read it there, from them.

Call the pediatrician — the part that isn’t optional

Don’t spend a fourth night deciding. Call, same day, if you see any of these:

  • Fever, at any age, and urgently in a young infant.
  • Fluid, pus or blood draining from an ear.
  • Ear pain that is clearly distressing the baby, or a child old enough to tell you their ear hurts.
  • Crying that gets markedly worse when they’re laid flat.
  • Refusing feeds, or noticeably less interested in eating or drinking.
  • Unusual lethargy or floppiness, or a baby who’s hard to rouse.
  • Any change in how they respond to sound, or in the cry itself.
  • Symptoms that arrive in the tail of a cold and are getting worse rather than better.

Also call if it’s simply been going on too long, or if your gut says something’s off. That instinct is not nothing, and no pediatric office has ever been annoyed by a parent who called about an ear.

And on the subject of anything you might give a baby for discomfort — dose, product, age, all of it: ask your pediatrician or pharmacist, not a blog and not the aisle. That includes the things sold specifically for teething.

What you can do while you wait for the callback

None of this treats anything. It buys a household forty-eight hours of function.

Split the night formally. One adult owns the baby, the other owns the morning and the field run. Both of you being half-awake for everything is how a week becomes a fortnight. Same doctrine as our colic-evening playbook, and it holds for every version of a broken night.

Protect the older kid’s sleep separately. The baby’s night isn’t negotiable this week; the ten-year-old’s is. Keeping the post-practice wind-down intact means one kid’s rough week doesn’t become two.

Cash in a carpool. This is the thing the team group chat is genuinely for, and everyone on it has had this week. “We’ve got a sick baby, can anyone grab Nico Tuesday” needs no further explanation.

Drop the optional stuff. The extra scrimmage, the make-up session, the thing you said yes to in June. All of it survives being skipped.

Don’t rebuild the whole sleep plan mid-week. Whatever’s happening will resolve or get treated. Making four structural changes during it means you’ll have no idea what worked.

Where the regression question gets answered properly

The one thing you can investigate from home is the regression side — and the answer is usually less mystical than “regression.” Most of what gets that label is a wake window the baby quietly outgrew: the awake stretches that worked last month now leave them either undertired at bedtime or wrecked by it, and both look identical at 2am. Betteroo’s breakdown of the nine-month awake stretches is the useful shape of that check, and there’s a version of it for every month either side.

Which is the same problem we keep landing on in this corner of the site: the information isn’t hard to find, but tonight’s actual numbers — this nap, this bedtime, this baby, in a week where practice moved to 6:15 — are. That’s the gap a plan fills. Around $20 a month, built for the baby-and-toddler range, and to be clear about the limits: it won’t touch an ear infection, and it isn’t trying to. Nothing here replaces the phone call. A tool, not magic.

FAQ: teething, ear infections and sleep regressions

How do I know if it’s teething or an ear infection?

You can’t know from home — the signs overlap heavily, and confirming an ear infection requires a clinician looking in the ear. If there’s fever, ear drainage, clear ear pain, worse crying when lying flat, or a rough turn after a cold, call your pediatrician rather than working it out yourself.

Can teething cause a fever?

Fever is not something to file under teething and wait out. Any fever in a baby is a reason to check in with your pediatrician, and in a young infant it’s an urgent one.

How long does a sleep regression last?

Commonly one to a few weeks, tied to whatever the baby is learning to do. If a rough patch is dragging on well past that, or came with any of the signals above, it’s worth a call rather than more patience.

Is my baby waking up because of the sports schedule?

Sometimes, indirectly — later, louder evenings can shorten a baby’s runway to bedtime. But don’t reach for that explanation before you’ve ruled out the medical one. Schedule problems don’t come with a fever.

Should I stop sleep training during teething or illness?

Ask your pediatrician about the illness question specifically. As a general matter, most families pause structural changes during a rough patch and resume once the baby is well, because nothing you learn during it is reliable anyway.

Can I send the baby to the field on a bad-sleep night?

Usually yes, if they’re well — a stroller in fresh air is often kinder than a bright house at 6pm, and our sideline bag plan for the kid in tow covers the low-stimulation version. If they’re unwell or waiting on a doctor’s call, stay home. The game is on Saturday too.
