Happy Father's Day Expectant Dads

Dr. Hakakha and Dr. Brown are authors of the new book Expecting 411: Clear Answers & Smart Advice for Your Pregnancy, which is written with both expectant moms and dads in mind.

They say fathers-to-be go through changes that rarely get discussed, and offer these 7 tips especially for them:

• Mind your own baby bump. Are you eating for two right along with your wife? Newsflash: Your wife will lose a lot of her weight automatically when she has the baby--you won't! Studies show expectant fathers often gain extra pounds of "sympathy weight" during their wife's pregnancy.

• Take one for the team. Get your TdaP shot as well as seasonal flu and H1N1 vaccines to protect your precious cargo, who will soon be joining the family. Seventy percent of babies who get whooping cough are infected by immediate family members like you.

• Baby yourself. Have you even been to the doc lately? Studies show many men ages 25-45 don't even have a primary care physician. Go get a checkup. Find out how you're doing, healthwise. Your baby needs a healthy dad who will grow old and wise.

• Mind your moods. Research shows that partners are not only at risk for gaining sympathy weight, but may also suffer postpartum depression. Seek help if you feel overwhelming feelings of sadness, lack of desire to be around family and friends, severe fatigue, or trouble eating or sleeping after delivery.

• Prepare for a dry spell. Hate to say it, but there can't be intercourse 6 weeks after the baby is born. The good news? Barring any health issues, you and your wife can have sex up until the last day before she delivers. And, no, sex does not trigger labor--that's an old wives' tale.

• Engage in baby talk. We now know that babies recognize their parents' voices inside the womb. So go ahead--sing Hank Williams songs, recite your favorite poem, or just shoot the breeze with your unborn baby. When your baby is born, she or he will already know you.

• Dads can nest too. Expectant dads are allowed to nest too--and often feel an overwhelming need during their wife's pregnancy to rev up the power tools. Feel free to paint, spackle, drill, and build to your heart's content--but avoid toxic materials and fumes in the baby's room.
