Decaf coffee is considered safe to drink during pregnancy.
There’s a decent amount of research to support the safe consumption of caffeine during pregnancy, so you can definitely get away with having decaf alternatives.
Standard guidelines for caffeine intake during pregnancy outline no more than 200-300 milligrams per day. This is equivalent to two standard cups of coffee, three cups of instant coffee, or up to six cups of tea.
Many pregnant people may prefer to avoid caffeine altogether during pregnancy just due to personal preference or comfort, so decaf coffee may serve as a good alternative that contains very little caffeine.
