Breastfeeding Questions: 13 Short, Sourced Answers

How often should I breastfeed a newborn?

Often — the CDC says a newborn is "breastfeeding often, 8-12 times per day (24 hours)," and "may want to eat as often as every 1 to 3 hours, including during the night."

On-demand, responsive feeding (following your baby's hunger cues rather than a fixed clock) is the general approach behind that range, not a strict timer.

How long should I breastfeed overall — is there a recommended age to stop?

There's no mandatory stopping age. The AAP states it "supports parents to continue breastfeeding their child through the second birthday, for as long as mutually desired by the nursing parent and child," after exclusive breastfeeding for about the first 6 months.

That's a floor for support, not a ceiling — the decision of when to stop belongs to the parent and child, not a fixed calendar date.

What is the best age to wean off breastfeeding?

There isn't one "best age" set by a medical body — the AAP's guidance (above) supports continuing through age 2 or beyond if both parent and child want to, which means the right time is a personal decision, not a fixed milestone.

Some families stop earlier for medical, practical or personal reasons; both continuing and stopping earlier than 2 years are within normal, supported choices.

Can I breastfeed while pregnant?

Generally yes. The AAP's guidance on nursing during a subsequent pregnancy gives "a qualified yes... depending on your medical history, your older baby's responses, your own feelings, and your milk supply."

One real precaution: the AAP notes that breastfeeding parents "who have miscarried previously or who have a history of premature delivery should stay in touch with their obstetrician and report any uterine contractions, since the nipple stimulation of breastfeeding may increase your risk of delivering too soon."

Expect changes, too — the AAP says "after the first few months of pregnancy, your milk supply will probably diminish somewhat, and the taste of your breast milk may change as well," which can lead an older baby to self-wean.

Does breastfeeding prevent pregnancy?

Only under specific, simultaneous conditions — this is called the Lactational Amenorrhea Method (LAM), and the WHO-affiliated guidance requires all three at once: your periods haven't returned ("amenorrhoea"), you are "fully or nearly fully breastfeeding," and your baby is "less than six months postpartum."

Under all three conditions, effectiveness is stated as "99% with correct and consistent use" and "98% as commonly used" — but if any one condition isn't met (periods return, feeds become less frequent, or your baby passes 6 months), LAM is no longer considered reliable.

What is mastitis, and when should I call a doctor?

Cleveland Clinic defines it as "a breast infection that causes your breast to become red, hard and swollen," most common "in the first three months of breastfeeding."

Watch for "breast pain or burning sensation that worsens when your baby nurses" plus "flu-like symptoms, including fever and chills" — call your provider if at-home care for engorgement doesn't help, or if you notice a new lump, nipple discharge, or symptoms that worsen after 24 hours of antibiotics or several days of home treatment.

Is caffeine safe while breastfeeding?

Yes, in moderation. The CDC states "a low to moderate amount is about 300 milligrams or less per day, which is about 2 to 3 cups of coffee," and that this level "usually does not adversely affect the infant."

At much higher intakes — "about 10+ cups daily" — the CDC notes "irritability, poor sleeping patterns, fussiness, and jitteriness have been reported in infants." The CDC also flags that "preterm and younger newborn infants break down caffeine more slowly," so parents of very young or premature babies may want to stay on the lower end.

What is "reverse cycling," and is it something to worry about?

Reverse cycling is when your baby "nurses frequently at night and less frequently during the day" — common when a breastfeeding parent returns to work or a baby starts childcare, and the pair make up for less daytime contact overnight.

It's generally described as a normal adjustment rather than a medical problem, as long as your baby is still getting enough milk overall — tracked by wet diapers and steady weight gain, not by how the feeds are distributed across the day.

What are the "three stages of weaning"?

No official body — WHO, AAP or otherwise — defines a fixed "three stages of weaning." This appears to be informal parenting-content shorthand rather than a clinical framework.

What's actually documented is a spectrum: weaning can mean dropping a single feed, gradually reducing frequency over weeks or months, or stopping abruptly — each with different physical and emotional adjustments, discussed below.

What is the best way to stop breastfeeding?

Gradual is generally easier on your body than abrupt. Dropping feeds slowly, one at a time over days to weeks, gives your milk supply time to decrease in step and lowers the risk of painful engorgement — the same kind of breast fullness that, left unmanaged, can contribute to mastitis (see above).

There's no single official protocol for pace beyond that general principle; how quickly you can go depends on your comfort, your baby's age, and how attached they are to particular feeds (bedtime and early-morning feeds are often the last to drop).

What happens physically when you wean?

Your milk supply gradually decreases in response to less frequent removal of milk — the basic supply-and-demand mechanism behind breastfeeding in general.

Some breast fullness or tenderness during the transition is common, especially if feeds are dropped quickly; that's the same discomfort the "gradual is easier" guidance above is meant to reduce.

Why are my nipples sore or cracked — is that normal?

Some tenderness in the first days of breastfeeding, while you and your baby are learning positioning and latch, is common. Pain that continues past those first days, or nipples that crack or bleed, usually points to a latch that needs adjusting rather than something to just tolerate.

Our breastfeeding positions guide covers latch technique in more depth if soreness continues.

How do I check if a medication is safe while breastfeeding?

In the US, the go-to free lookup is LactMed, the National Library of Medicine's Drugs and Lactation Database, run by the National Institutes of Health — it covers drug levels in breast milk, possible infant effects, and safer alternatives where relevant.

Always confirm with your own doctor or pharmacist for your specific situation rather than relying on a database lookup alone, especially for prescription medications or ongoing treatment.
