Frequently Asked Pregnancy Caffeine Questions

What is the official ACOG caffeine limit for pregnant women?

The American College of Obstetricians and Gynecologists recommends a maximum of 200mg caffeine per day for all pregnant trimesters, equivalent to roughly one standard 8oz brewed coffee.

Does caffeine cross the placenta and affect the fetus?

Caffeine easily passes through the placenta. Excess intake over 200mg daily may increase risk of low birth weight, preterm birth, or fetal sleep disturbance.

What are good zero-caffeine substitutes for coffee?

Rooibos tea, chamomile herbal tea, warm milk, fruit infused water, decaf oat latte, and homemade fruit smoothies are perfect safe alternatives for expecting mothers.

Is small amounts of caffeine safe during breastfeeding?

Under 300mg daily is generally safe for breastfeeding mothers; high caffeine may cause infant fussiness, poor sleep and colic symptoms.
