Can you use Mountain Dew daily while pregnant?
Mountain Dew should be an occasional treat rather than a daily beverage during pregnancy. Consider limiting consumption to a few times per week at most, and opt for caffeine free or lower sugar alternatives when possible.

What are pregnancy safe alternatives to Mountain Dew?
Sparkling water with a splash of citrus Juice, caffeine free Ginger Ale, or flavored seltzer waters are great alternatives. For a citrus fix, try diluted Orange Juice mixed with sparkling water.
Why does Mountain Dew get a D+ grade?

Is the caffeine in soda safe during pregnancy?
Caffeine in soda is safe during pregnancy when kept under 200mg daily. A 12oz Mountain Dew contains about 54mg of caffeine, so you'd need to track your total daily intake from all sources including coffee, Tea, and chocolate.
