I absolutely love when people use last names as first names for their babies. It's a great way to give your baby a name that is classic yet unique. Even if you were to name your baby "Smith" (which is one of the most common last names there is), it still sounds totally fresh when being used as a first name, but doesn't venture too far out there in the uniqueness category since it's still a name people are used to hearing - even if it is only as a last name. I checked out a list of the most common last names in the U.S. (based on census data) and got so many great baby name ideas in the process. In addition, I added a few last names of famous actors, writers and the like to round out my list. Here are 40 of my favorite last names that make great first names! - By Lauren Hartmann

When I'm out with my three kids, I often get some bizarre questions and comments. One of the most common question is, "Are all of those kids yours?"

On the surface, it seems like an innocent question, but it is rife with condescensention and pity. I've heard the question enough to understand what they're really saying is, "I can't believe that a dad is out with children by himself." After I assure them that my wife is healthy and alive, they smile and give me a backhanded compliment.

"You're a good dad."

Really? Are the expectations for dads so low that showing up in public with your kids, makes you Dad of the Year?

I know that many dads have experienced similar scenarios. While we try to be polite and respond respectfully, having strangers question our parenting abilities can be annoying.

The next time you observe a dad out with his children, please exercise some restraint and avoid saying the following five things:

1. "Do you know what you're doing?"

You've got to give props for the originality of this form of unique and unusual punishment. A parent in Murray, Utah made their daughter wear old and dated outfits from their local thrift store for bullying one of her fellow students for how she dressed.

According to Fox News, Ally - the woman who acts as the girl Kaylee's mother (she is in a long-term relationship with the girl's father) - received an email from Kaylee's school saying that the young woman had been harassing one of the students for weeks for how they dressed. "She would take her out on the playground and call her names, and tell her she was a slob and tell her she dressed like a sleaze," Ally said. "Someone not wanting to go to school anymore based off of something that one other little person said to them. I mean, that's huge, that's damaging."

That's when Ally decided that Kaylee needed to be taught a lesson, "she really needs to know that this had such an effect on

Thinkstock / The BumpNew research appearing in the American Journal of Human Biology suggests that a woman's reproductive functions may be tied to her immune status. While previous studies have found this same immune and reproductive association in men, this is the first time the association has been found in females.

Beginning by speaking of animals in general, Kathryn Clancy, anthropology professor at the University of Illinois who led the research, said that first and foremost, "an animals energetic resources must be carefully allocated. The body's first priority is maintenance, which includes tasks inherently related to survival, including immune function." From there, Clancy said, that any remaining energy is dedicated to reproduction. And due to a "resource allocation" to maintenance and reproductive efforts, often times environmental stressors can lessen the available resources.

Jupiter Images / The BumpEven if your guy is super-pumped to be a Dad, chances are he's a little freaked out too. Here are a few of the biggest new-daddy fears (and some things you both can do to ease the pressure).

FEAR #1: "Will I do everything right?" --Andrew
MOM TIP: Let him know that it's okay to be clueless. "Any father can care for his child," says psychotherapist Tammy Gold, founder of Gold Parent Coaching. If he doesn't know how something works, help him learn and then back off to give him a shot. Practice makes perfect.

FEAR #2: "I fear not being able to properly provide for my family once baby is here." --Brian
COUPLE TIP: Do your homework to get a feel for what you'll really need to spend. "You can get a rough enough estimate," says Gold. "Then make a baby budget -- no different than how you'd make a house budget." Having a written game plan can relieve some serious stress.

FEAR #3:

Researchers at Schneider's Children Medical Center studied over 50 children (age 6-12) who had been diagnosed with ADHD between 2008 and 2009. These children were compared to two control groups: the first consisted of healthy (non-ADHD) siblings of ADHD children and the second control group was composed of children of similar ages without ADHD. Researchers also presented a questionnaire to both parents of children in all three groups that addressed: demographic, medical and perinatal findings, as well as feeding history during their child's first year of life. Parents were also given a validated adult ADHD screening questionnaire.

Thinkstock / The BumpDon't do this. Don't do that. With all the pregnancy "advice" out there, it's hard to know what to believe -- or whom to believe. But remember, every pregnancy is different, so follow your doctor's orders above anything else.

Myth 1: Eat three healthy meals a day
False! You should be eating six or seven small meals (every two to three hours). "Eating frequently and from various food groups will keep your blood sugar in a constant range, which is healthy for you and your baby," says Stuart Fischbein, M.D., coauthor of Fearless Pregnancy.Don't obsess about food and don't diet. What was good for you pre-pregnancy is good for you now. And yes, that includes an ice cream sundae with butterscotch sauce if you so desire.

Myth 2: Decaf only
False! One small cup of coffee a day is perfectly fine. While a recent study at McGill University in Montreal did

On Wednesday, a Murry, Utah-based woman named Ally Olsen, 41, discovered that her fiancé’s 10-year-old daughter, Kaylee, was bullying a classmate. Kaylee’s teacher had emailed Olsen, explaining that the girl had been teasing a student for the past three weeks because of how she dressed. As a result, the victim no longer wanted to come to school.
