Fortunately (or unfortunately, depending on how you look at it), there’s no scientific research that proves you get flakey during pregnancy. But even if “pregnancy brain” is just a myth, there are still tons of women who complain of feeling more forgetful or spaced out during their pregnancy. If you’re experiencing memory lapses or periods of forgetfulness, chances are your fellow moms-to-be can relate. So what’s to blame? Hormonal changes, lack of sleep, and/or the distractions of spending a lot of time thinking (and stressing) about baby are the likely causes. Save your sanity by writing things down and making lists, along with snacking regularly and getting lots of rest. Also, be sure to take your prenatal vitamins — they contain ingredients that help boost mental sharpness. Don’t worry, it’s annoying, but it isn’t fatal or permanent.
