Coffee

Yes, it is perfectly safe to have caffeine when you're breastfeeding. Though the caffeine you eat and drink does end up in your breast milk, most research suggests that amount is less than one percent of what you ingest. If you do have more than one cup a day, minimise the amount in your breast milk at any one time by spreading your coffee intake over the course of the day or opting for espresso drinks such as lattes that have less caffeine than regular brewed coffee. It's very unlikely that your baby will show any effects from the caffeine you drink. But if you feel strongly that your baby is excessively cranky after you drink coffee, you can try an (admittedly challenging) experiment. Take caffeine out of your diet for a week and see if there is a change in your baby's behaviour. Then put caffeine back into your diet and see if she reverts back to the irritability. If she does, you have your answer. But the bottom line is that your baby is likely unaffected by your daily pick-me-up. So you can enjoy your cup of coffee without worrying about it.
