Choosing the Right Thermometer for Your Family

When a child feels warm at 2 a.m., the last thing you want is to second-guess your thermometer. Each type has real strengths — the right choice depends on who you're measuring and how often.

The main types at a glance

• No-touch forehead (infrared): Reads in about a second without waking a sleeping child. Ideal for frequent checks and squirmy toddlers. (PPB-110F)
• Ear + forehead combo: Flexibility of both methods in one device — ear readings tend to track core temperature closely in kids over 6 months. (PPB-210B)
• Digital stick thermometers: The accuracy benchmark for oral, underarm, and rectal readings, at the lowest price point. A flexible-tip version adds comfort. (see all thermometers)

What actually counts as a fever?

A fever is generally a temperature of 38.0°C (100.4°F) or higher. Normal body temperature varies by measurement site — ear and rectal readings run slightly higher than oral, and underarm runs slightly lower — so always note how you measured, not just the number.

When to call a healthcare provider

• Any fever in a baby under 3 months — contact a provider right away.
• Fever lasting more than 2–3 days, or above 40°C (104°F).
• Fever with stiff neck, unusual drowsiness, difficulty breathing, persistent vomiting, or a rash that doesn't fade with pressure — seek urgent care.

Remember: how your child looks and behaves matters more than the exact number. A playful child with 38.5°C is usually less concerning than a listless one at 38.0°C.

Thermometer care tips

Clean the sensor or tip after each use (alcohol wipe for probes; soft dry cloth for infrared lenses), store it in its case, and replace batteries yearly so it's ready when you need it.
