A recent study has shown that women who are pregnant are more likely to receive unsolicited advice from strangers than any other group. This advice ranges from the helpful (“you should really be eating more spinach”) to the unsolicited (“ you’re going to have a C-section, I just know it”). While most of this advice is well-meaning, it can be overwhelming and even stressful for expectant mothers. So the next time you’re tempted to offer unsolicited advice to a pregnant woman, remember that she is probably already inundated with enough advice – from professionals and strangers alike.

“Pregnancy is a blessing and a miracle.”
“Pregnant women should eat for two.”
This old wives’ tale is not supported by science. In fact, pregnant women need only about 300 extra calories a day in their second and third trimesters. Eating for two can lead to excess weight gain, which can be difficult to lose after the baby is born. So, women should be careful not to overindulge during pregnancy.
