Breastfeeding and stimulants: what you need to know about alcohol, caffeine, and tobacco

Many breastfeeding mothers wonder what is safe to consume. Here's the evidence on alcohol, caffeine, and tobacco — no guilt, just the facts.

ALCOHOL AND BREASTFEEDING

A common myth is that alcohol helps with milk flow and calms babies. In reality, the opposite is true. Alcohol inhibits the milk ejection reflex by interfering with oxytocin — the hormone responsible for milk release from the ducts. While a baby might fall asleep faster after an alcoholic feeding, their sleep is lighter and shorter, and they wake up agitated and irritable.

Regular exposure to alcohol through breast milk is associated with delayed motor development, apathy, and poor growth in babies.

What to do:

• If you want to drink, breastfeed first, then wait at least 2 hours per unit of alcohol before feeding again.
• If you know you're going to drink a lot, express your milk beforehand and offer it instead.
• A simple rule: if you can smell the alcohol, it's still present in your milk. Note on beer: while barley malt may have a slight effect on milk production, the alcohol content outweighs any benefit — even in low-alcohol beers.

CAFFEINE AND BREASTFEEDING

Caffeine passes in small amounts into breast milk. In adults, it is eliminated in about 5 hours, while in newborns, the same amount can take up to 96 hours to be eliminated, with this time reducing to about 14 hours around 3 to 4 months of age, as their metabolism develops.

Too much caffeine can cause irritability, poor sleep, and restlessness in your baby. Caffeine is found in coffee, tea, cola, energy drinks, and some medications (including some cold products and pain relievers).

What to do:

• Up to 200-300 mg of caffeine per day is considered safe during breastfeeding — about 1 to 2 cups of coffee.
• If your baby seems agitated or sleeps poorly, try reducing it and see if it helps.
• Tea contains less caffeine than coffee and is a milder alternative.

SMOKING AND BREASTFEEDING

Nicotine passes directly into breast milk. Smoking reduces prolactin levels — the hormone that stimulates milk production — meaning that mothers who smoke tend to produce less milk and stop breastfeeding earlier.

In babies of mothers who smoke more than 10 cigarettes a day, the risk of respiratory diseases, colic, and sudden infant death syndrome (SIDS) is significantly increased.

What to do if you can't quit:

• Smoke as little as possible — every reduction helps.
• Always smoke after a feeding, never before.
• Smoke outdoors, away from your baby.
• If you use nicotine patches, choose the lowest dose and remove them at night.
• If you use nicotine gum, wait 2 to 3 hours after use before breastfeeding. The good news: if you quit completely, nicotine disappears from your milk within 12 hours.

PASSIVE SMOKING

Non-smoking mothers regularly exposed to cigarette smoke also breastfeed for shorter periods and encounter more difficulties

with breastfeeding. Their babies face the same health risks as those of smoking mothers — including higher rates of respiratory diseases and a greater likelihood of becoming smokers themselves in adulthood.

What to do:

• Ask anyone who smokes to do so outdoors, away from you and your baby.
• If you hire an assistant, confirm that they do not smoke.
