Some information is easier to find before you need it: the after-hours number, the date on a milk container, and what your baby’s care team wants you to watch for. Keep this page handy and add the instructions specific to your baby.

Numbers to save in your phone.

Ask your pediatrician’s office and health plan which nurse advice line to use, whether it is available after hours, and where to go when the office is closed. Save the contact as “Baby’s nurse line” and share it with anyone helping care for your baby. There isn’t one universal nurse number.

Fever: the method matters.

Fever cutoffs from Seattle Children’s. These are readings, not a conversion chart.

Children’s fever readings by measurement method
Method & ageFever at or above
Oral Age 4+; able to cooperate100°F37.8°C
Ear Age 6 months+100.4°F38°C
Rectal Most accurate for young infants*100.4°F38°C

Younger than 3 months? A rectal reading of 100.4°F (38°C) or higher needs medical care right away. Don’t wait for a higher number.

Report the actual reading and method. Don’t add or subtract a degree. A lower reading does not rule out serious illness.

*Ask your clinician how to measure safely. Some children, including those with weakened immunity, should avoid rectal measurements. Follow their individual plan.

Cutoffs: Seattle Children’s. Age/method guidance: AAP. Urgent infant guidance: Johns Hopkins.

Published fever definitions can differ slightly, especially for oral readings. This card uses Seattle Children’s method-specific cutoffs. Follow your child’s clinician’s instructions. Ear readings are unreliable under six months; oral readings are not for babies. For an unwell baby, call promptly even below a cutoff.

Fever: age, measurement, and how baby looks matter.

Do not wait for a higher number or the time limits below if your baby looks ill, is feeding poorly, or has fewer wet diapers. Call for guidance. For severe trouble breathing, unresponsiveness, or a life-threatening emergency, call 911.

When to call about fever — based on Johns Hopkins guidance
Age / situationTemperature or timingWhat to do
Younger than 3 months100.4°F (38°C) or higher, measured rectallyContact the pediatrician immediately and get medical care right away.
3 months to younger than 2 yearsFever of 100.4°F (38°C) or higher lasting more than 24 hoursCall the clinician. Call sooner if your child seems unwell.
2 years and olderFever of 100.4°F (38°C) or higher lasting more than 3 daysCall the clinician. Call sooner for concerning symptoms.
Any ageRepeated temperatures above 104°F (40°C)Call the clinician right away.

Sources: Johns Hopkins: Fever in children and Measuring a baby’s temperature. These are call triggers, not an “all clear” below the cutoff. Follow the child’s own clinician’s instructions.

Tell the nurse the actual number, how you measured it, baby’s age, and symptoms. Ask your pediatrician to demonstrate the right method. An ear thermometer is for six months and older; rectal readings are most accurate for young infants. Don’t add or subtract degrees to convert between methods.

Wet and dirty diapers: a guide for the beginning.

This first-week example draws on NHS and AAP newborn guidance. Diaper counts are one part of feeding assessment, alongside weight and how baby is doing. They cannot prove that everything is okay on their own.

Early diaper guide — counts per 24 hours; stool column is for breastfed newborns
Baby’s ageWet diaper guideBreastfed newborn stool pattern
Day 1At least 11–2 black / dark green meconium stools
Day 2At least 21–2 black / dark green meconium stools
Days 3–4At least 3 on day 3; 4 on day 4At least 2 stools, changing green to yellow
By days 5–76 or moreAt least 3–4 yellow, loose stools

Sources: Dartford and Gravesham NHS: early diaper pattern, AAP: breastfed newborn output, and NHS Healthier Together: bottle-feeding patterns.

Breastfed, formula-fed, and combination-fed babies can have different stool patterns. Formula-fed stools may be firmer and less frequent. This is not an ongoing stool quota for older babies. If wet diapers are fewer than expected, baby is difficult to wake for feeds, or you are worried about intake, contact the care team promptly rather than waiting to fill the next row.

Breast-milk storage: label the date, keep the conditions.

This table is for plain expressed breast milk at home for healthy, full-term infants. It does not apply to formula or mixed breast-milk/formula bottles. A hospital may give different instructions for a premature or medically vulnerable baby.

Expressed breast milk — CDC home-storage guidance
Milk typeRoom: 77°F / 25°C or colderFridge: 40°F / 4°C or colderFreezer: 0°F / −18°C or colder
Freshly expressedUp to 4 hoursUp to 4 daysWithin 6 months is best; up to 12 months acceptable
Thawed, previously frozen1–2 hoursUp to 24 hours, starting when fully thawedDo not refreeze
Left from a feedingUse within 2 hours after baby finishesSame 2-hour limitDo not save for later by freezing

Source: CDC: Breast milk storage and preparation and its storage chart.

Once warmed or brought to room temperature, use milk within 2 hours. Follow the earliest applicable deadline; cooling it again doesn’t restart a clock. Label the expression date, store toward the back of the fridge/freezer, and never microwave breast milk.

A couple of Kassandra’s practical picks.

Kassandra liked reusable Zip Top breast-milk bags with the freezer tray. The maker identifies these specific bags as intended for breast milk and freezer use. Follow their cleaning and sanitizing instructions and the milk-storage limits above. A “microwave-safe” container label does not mean you should microwave breast milk.

Water-dissolvable food labels were another useful detail: write the expression date and time, put the label on the outside, and check that it stays readable for the planned storage conditions. Add baby’s name for childcare. Keep the labeling simple enough that the next person can understand it.
