The latest research suggests that drinking caffeinated drinks during pregnancy will raise your risk of giving birth to baby with a lower birth weight.

Though caffeine has been linked to having adverse effects on pregnant women, a limit has been set on what pregnant would should consume, if they can’t do without a caffeine kick. But, there have been a fair share of conflicting reports from differing health organization as to what pregnant women can safely consume. The World Health Organization recommended a limit of 300 milligrams of caffeine a day (which is about three 8-oz. cups of regularly brewed coffee), while the American College of Obstetricians and Gynecologists recommended 200 milligrams per day in 2010. The 200 milligram limit, they stated, would not increase the risk of miscarriage or preterm birth.

But this latest study, which was published in the BMC Medicine journal, found that a child lost between three-quarters of an ounce to a full ounce in birth weight for every 100 milligrams of average daily caffeine intake from all sources by the mother. Researchers collected data on nearly 60,000 pregnancies over a 10-year period. And while they did find an association between caffeine and low birth weight, a correlation with caffeine consumption and the risk of preterm birth could not be found.

The study author, Dr. Verena Sengpiel of the Sahlgrenska University Hospital in Sweden, said that the findings were not definitive because the study was observational — so that correlation (in this case) does not equal cause. What Sengpiel is able to suggest, though, is that women should put their caffeine consumption “on pause” while pregnant, or at least stay below two cups of coffee per day.

On the short list of things you have to give up when you get pregnant is your evening glass of wine right? Well some Danish researchers say maybe not.

For their newly released study, published in medical journal BJOG, the researchers surveyed the drinking habits of over 1,500 women and then analyzed their children’s intelligence test results.

According to the report, mothers who consumed small amounts of alcohol during the early stages of pregnancy had children with no visible signs of mental problems at age five. Even up to eight drinks per week was not associated with significant mental impairments. The kids whose moms drank nine or more drinks per week, however, were more likely to have lower attention spans.

But before you pop the wine cork, know that the research only observed the children up to the age of five. The  researchers themselves warned that their findings aren’t proof that light to moderate drinking is safe for baby. “As alcohol is a known teratogen [meaning it causes birth defects], it remains the most conservative advice for women to abstain from alcohol during pregnancy,” they said in a release.

And while there has been other research suggesting light drinking may be okay during pregnancy, there are also studies that say no amount of alcohol during pregnancy is proven safe. Sounds like more research needs to be done to reach a real conclusion.

What are your thoughts on drinking while pregnant? Would you do it in moderation? Or say no way?

You’ve probably been told to avoid nail polish with the chemicals dibutyl phthalate (DBP), toluene, and formaldehyde while you’re pregnant, to avoid exposing baby to the chemicals. Should be as simple as checking the bottle before you get a mani, right? Well, not exactly.

The California Environmental Protection Agency’s Department of Toxic Substances Control (DTSC) recently did a study of nail products for sale in the San Francisco Bay Area and tested them for DBP, which can cause hormone production problems in a fetus; toluene, which can cause reproductive issues, headaches, itchy eyes and more; and formaldehyde, which can cause breathing problems and could cause cancer (all scary!).

25 nail products were randomly collected from distributors to nail salons. Of those items, 12 claimed to be free of at least one of those chemicals, and seven claimed to be free of all three (“three-free”). But when the researchers tested what was inside the bottles, they found that many were mislabeled. 10 of the 12 products that said they were toluene-free actually did contain toluene and five of the seven that said they were three-free couldn’t be proven to live up to their claims.

So, if you’re pregnant, avoid these nail polishes — all salon-only brands (not sold in stores) which the Associated Press says were among the mislabeled ones:

Sation 99 basecoat, Sation 53 red-pink nail color, Dare to Wear nail lacquer, Chelsea 650 Baby’s Breath Nail Lacquer, New York Summer Nail Color, Paris Spicy 298 nail lacquer, Sunshine nail lacquer, Cacie Light Free Gel Basecoat, Cacie Sun Protection Topcoat, Golden Girl Topcoat, Nail Art Top-N-Seal and High Gloss Topcoat

The DTSC is calling for manufacturers to accurately label their products and for the industry to make measures to keep nail salon workers safer from these chemicals.

So who here got highlights while pregnant? Kourtney Kardashian is catching some flak about it. Kourtney, who’s now pregnant with baby number two, recently blogged about the decision to highlight her hair while pregnant and even went so far as to explain that she made special efforts to make sure she was doing it safely.

She wrote on her blog: “I did research about doing anything to the color of my hair while pregnant and followed all of the guidelines from my doctor and took the proper precautions necessary. I highlighted my hair (which is considered the safest form of hair color while pregnant) and NOT to the root, so nothing ever touched my scalp. I also used products that did not contain any ammonia. It is also recommended to be in a well-ventilated area as well as being at least in your second trimester, and I followed both of those rules. Anyone who knows anything about me knows that I take caution in all the products I use all the time, but especially when pregnant.”

We’ve talked to a medical expert in the past, who basically said, if you’re going to do it, do it the way Kourtney did: wait until after the first trimester, do highlights instead of dyes so it doesn’t touch your scalp and go ammonia- and peroxide-free. (In fact, we wonder if Kourtney did her research on The Bump!) But still, some commenters on Kourtney’s blog are calling her selfish for even risking it.

What do you think? Is it selfish to color your hair while pregnant? Or are people overreacting?
