Caffeine and breastfeeding

If you’re breastfeeding two things are almost certain: you’re going to feel thirstier than usual, as your breast milk is largely manufactured from fluids you consume; and you’ll be more tired, because breastfed babies usually need to feed more often and the feeds themselves can take longer.

Unfortunately, both of these factors can make you crave coffee – and if you’re drinking more than a couple of cups a day it could have negative consequences. Coffee contains caffeine, which is a diuretic – this means it’ll increase your urine output – valuable fluids that should be going into your breast milk. And keep in mind too that caffeine is also a stimulant: that’s why it makes you feel more alert. Trouble is, it’ll cross into your breast milk, making your baby jittery and potentially disturbing his bedtime routine and sleep patterns. It could also potentially make your breast milk taste or smell differently, and there’s some evidence that it can lower the amount of iron in breast milk.

Similarly, if you’re drinking too much coffee you may find yourself contending with the jitters when you really should be getting some much-needed rest, so try to limit your coffee consumption to a maximum of 300mg per day (tow to three cups of regular strength coffee). Don’t forget caffeine comes from other sources too, including soda and energy drinks. There’s even a small quantity in decaf coffee.

It’s important to drink plenty of fluids when you’re breastfeeding, but they need to be the right kinds of fluids. Water is most definitely best, followed by herbal or fruit teas and fresh fruit juice. Similarly to caffeine, you should avoid alcohol when breastfeeding, as this will cross into your breast milk.
