What is the best baby thermometer?

If you’re buying one thermometer specifically for a baby, I’d prioritize a digital rectal thermometer over the fancy no-touch models. The American Academy of Pediatrics considers rectal temperature the most accurate method for infants, especially under 3 months.

My top picks

• Frida Baby Rectal Battery Thermometer - $14.99 (Target)

• CVS Digital Rectal Thermometer - $17.59 (CVS)

• Safety 1st 5-Second Read Rectal Thermometer - $12.79 (Target)

• Braun Baby 8-second 3-in-1 Digital Thermometer - $19.86 (Walmart)

• Best overall for a newborn/young infant: Frida Baby Quick-Read Rectal Thermometer — fast 10-second reading, flexible tip, and designed specifically for rectal use.

• Best inexpensive option: CVS Digital Rectal Thermometer — straightforward, inexpensive, and has a flexible tip and insertion guide.

• Best budget alternative: Safety 1st 5-Second Read Rectal Thermometer — particularly appealing if you want a quick reading and over-insertion indicator.

• Best one for the whole family: Braun 3-in-1 Digital Thermometer — can be used rectally, orally, or underarm, though I'd still use rectal measurement for a young baby when accuracy matters.

One important point: I'd treat a forehead/no-touch thermometer as convenient rather than your primary thermometer for a very young baby. And ear thermometers aren't recommended for babies under 6 months because their ear canals are too small for reliable readings.

If your baby is under 3 months old, a rectal temperature of 100.4°F (38°C) or higher warrants contacting the pediatrician immediately.

If you tell me your baby's age (e.g., newborn, 3 months, 6 months, 1 year) and your budget, I can narrow it down to the single best choice.

The absolute best baby thermometer depends heavily on your child's age, though pediatric experts overwhelmingly agree that rectal readings are the gold standard for accuracy in newborns and infants under 3 months.

According to reviews from trusted platforms like Forbes Vetted and BabyGearLab , top-performing models balance professional-grade accuracy with quick reading times.

The best baby thermometer depends entirely on your child's age, as pediatricians consider rectal readings the gold standard for infants under 3 months , while in-ear or no-touch forehead scanners are highly recommended for older, squirming babies.

• 0 to 3 Months: Rectal thermometers provide the only truly accurate core body temperature.
• 3 to 6 Months: Rectal or forehead artery scanners are preferred.

If your baby is under 3 months: I'd specifically get a rectal digital thermometer rather than relying on a forehead or ear model. A rectal temperature of 100.4°F (38°C) or higher in a baby 3 months or younger warrants calling the pediatrician immediately.

If you tell me your baby's age (newborn, 3–6 months, 6–12 months, etc.) and your budget, I can narrow it down to the single best one to buy.

When it comes to babies (especially under 12 months), the American Academy of Pediatrics (AAP) states that rectal temperature measurement is the gold standard for accuracy.

Depending on your budget and how you prefer to take the reading, here are the top-rated baby thermometers on the market:
