How much caffeine passes into breast milk?

Answered by Douglas Hiatt

Caffeine is a stimulant found in many beverages and foods, including coffee, tea, energy drinks, and chocolate. It is known to pass into breast milk, but the amount that actually reaches your baby is relatively small.

On average, breastfeeding mothers who consume caffeine will pass about 1.5% of the amount they consumed into their breast milk. This means that if you drink a cup of coffee containing 100mg of caffeine, your baby would receive approximately 1.5mg of caffeine through breastfeeding.

It’s important to note that caffeine can affect babies differently, and some infants may be more sensitive to its effects than others. Premature babies, younger infants (under six months old), and those with certain health conditions may metabolize caffeine more slowly, resulting in it staying in their system for longer periods of time.

If your baby is premature or has health issues, it may be wise to limit your caffeine intake or speak with your healthcare provider to determine the best approach.

Additionally, the effects of caffeine on babies can vary. Some infants may experience irritability, difficulty sleeping, or fussiness if they consume caffeine through breast milk. Others may not show any noticeable effects. It’s important to pay attention to your baby’s behavior and adjust your caffeine intake accordingly if you notice any adverse reactions.

In my personal experience, I found that my baby was sensitive to caffeine when I consumed it in high amounts. I noticed that she became fussy and had trouble falling asleep after I had a couple of cups of coffee. To alleviate this, I reduced my caffeine intake and switched to decaffeinated beverages when I wanted a warm drink. This seemed to help, and my baby’s sleep patterns improved.

To summarize, while caffeine does pass into breast milk, the amount that reaches your baby is relatively small, about 1.5% of what you consume. However, the effects of caffeine can vary among infants, especially those who are premature, younger than six months, or have certain health issues. It’s important to pay attention to your baby’s behavior and adjust your caffeine intake if needed.
