A baby's sleep may not suffer just because her mom likes a daily cup of coffee, a new study suggests.
The findings, experts say, don't give the OK to heavy caffeine intake during pregnancy or breastfeeding. But they are in line with research suggesting that moderate amounts of caffeine may not pose a danger.
Small studies over the years have come to mixed conclusions on whether caffeine during pregnancy was linked to increased risks of miscarriage or premature birth.
But more recently, larger studies have failed to show any heightened risk. And in 2010, the American College of Obstetricians and Gynecologists (ACOG) said that 200 milligrams of caffeine a day -- about the amount in a 12-ounce cup of coffee -- probably did not carry pregnancy risks.
