You can see the caffeine amount in the different coffee types in this table from mayoclinic:

Espresso, restaurant-style 1 oz. (30 mL) 40-75 mg
Espresso, restaurant-style, decaffeinated 1 oz. (30 mL) 0-15 mg
Generic brewed 8 oz. (240 mL) 95-200 mg
Generic brewed, decaffeinated 8 oz. (240 mL) 2-12 mg
Generic instant 8 oz. (240 mL) 27-173 mg
Generic instant, decaffeinated 8 oz. (240 mL) 2-12 mg

The Nutrition Effects of Caffeine when Breastfeeding?

If you drink a lot of coffee you might experience that your child is very active and awake because the sleep doesn’t last long. This might be because your child is plagued with constipation and colic.

If this is the case when breastfeeding, you need to either skip coffee or change to decaf and also change drinking cola to something else without caffeine if you drink a lot of cola (a lot of us are actually).

There is a widespread myth that caffeine will decrease your milk supply, and even though you probably stumbled across this several times I have to state that there is no evidence that caffeine will decrease your milk supply. After all, there have been a lot of research on the subject and a lot of breastfeeding moms drinks coffee so it should been rather easy to document any effect of caffeine on the milk supply, but there haven’t been found any in the numerous studies throughout the years. The study (Nehlig & Debry, 1994)   actually indicates the opposite which is quite ironic.

Even though your breast milk supply will not decrease because of caffeine, your breast milk will change the wrong way if you drink too much caffeine.

Breast milk of women who drink coffee during the pregnancy and breastfeeding will make their breast milk contain 1/3 less iron compared to the women who doesn’t have the same regular caffeine intake.

Avoid caffeinated drinks and foods will improve nutritional quality of the breast milk!
