What the sources say
CDC's pregnant-traveler guidance says no studies or case reports show fetal harm when a pregnant person travels briefly to high elevations. MotherToBaby (citing ACOG) says exercise at or above 6,000 feet is not recommended in pregnancy because of lower oxygen levels. The sources reviewed do not address breastfeeding at altitude; ask your clinician if you plan strenuous activity at elevation.
