Pregnancy Week by Week

Get a window on what’s happening in your pregnancy, week by week. From week four to week 42, your baby is experiencing a miraculous transformation from a clump of cells to a fully formed (and totally cute) newborn. Just imagine, as early as five weeks, your baby is already starting to form major organs (heart, stomach, liver, and kidneys) and systems (digestive, circulatory, nervous). By eight weeks, your raspberry-sized womb-mate is moving her arms and legs. At the beginning of your second trimester (week 14), your wee one is sucking his thumb. By week 28, the first week of the third trimester, baby (now as big as an eggplant) is prepping for breathing, developing his eyesight and packing on pounds in anticipation of life outside the womb. Each week is a new miracle. Less miraculous is how a mom-to-be may feel. Pregnancy Week-by-Week charts your baby’s development but also lets mom know what she might be feeling during each week of her pregnancy. Pregnancy week by Week includes everything mom needs to know to feel a sense of control over her pregnancy. Each week offers a complete guide to what you might feel, your must-do’s, your nice-to do’s, and answers and advice on everything pregnancy-related. Plus each week’s guide offers tips on maintaining a healthy and comfortable pregnancy from strategies on coping with pregnancy symptoms (morning sickness anyone?) to ideas for healthy eating, and pointers on talking to your OB. Let us guide you along your pregnancy, week by week.

Q&A: How to decrease SIDS risk?

What can I do to decrease my baby's risk of SIDS?

Re: What can I do to decrease my baby's risk of SIDS?

The Bump Expert

Every parent knows about SIDS (sudden infant death syndrome). It's rare, but probably a parent's worst nightmare. By definition, SIDS has no known cause -- and a very small percent of babies do die during sleep in their first year for no apparent reason. The American Academy of Pediatrics reports that nearly 2,500 babies die from SIDS each year in the US. The best way to decrease your baby's risk is to always keep him in a safe environment, including when he's sleeping... which he does a lot!

Lay baby on his back to sleep
The American Academy of Pediatrics (AAP) recommends putting babies to sleep on their backs. Studies show that more babies die when put to sleep on their stomach. We don't totally understand why this is, but it's simply a fact that babies are safer on their backs. Tummy time is fine when babies are awake (and important for exercise and development), but not for unsupervised sleep.

Get a good crib and firm mattress
Make sure your crib complies with current safety standards and has a firm mattress and well-fitting sheet.

Avoid fluffy bedding – including bumpers
You may think bumper pads are cute, but the AAP recommends against using them at all. While bumpers seem like a way to keep baby safe, studies found that they can suffocate, entrap and even strangle babies during sleep. There's also no evidence that says bumpers prevent injuries. Basically, stay away from anything that your baby could get trapped under when he wiggles around.

Take everything out of the crib
Don't worry about using special pillows and equipment to make your baby comfy -- he's just fine flat on his back. Never cover your baby's head with a blanket, avoid loose-fitting PJ's, and keep cuddly toys, blankets, pillows and stuffed animals out of the crib. If you want to use a light blanket to swaddle, that’s fine, but nothing else should be in the crib.

Same room, different bed
While you may want to cuddle with baby at night, this isn’t the best idea. Bed-sharing can expose your baby to additional risks, such as suffocation, asphyxia, entrapment, falls and strangulation, since the situation does not meet sleep safety standards. One study found that 13 percent of the surveyed SIDs victims died while bed-sharing. Another found that though breastfeeding helps reduce baby's SIDS risk, co-sleeping does not. The AAP does recommend room-sharing, where baby sleeps in the same room but on a separate surface. There is evidence that this arrangement decreases the risk of SIDS by as much as 50 percent, since a parent can keep a closer eye on baby.

Turn down the temp
Don't let baby get overheated -- he's just fine covered with a light blanket or a sleep sack. Studies show that heated bedrooms increase SIDS risk by about 4.5 percent, compared to non-heated rooms. Keep the room between 65 and 70 degrees to keep baby comfortable and safe.

Don’t smoke
Be sure to place the crib somewhere smoke-free. In fact, keeping baby away from smoke in general is a good idea – especially when they're still in the womb. Researchers have found that smoking during pregnancy nearly doubles the chance of SIDS for babies.

Seats are for sitting
SIDS used to be called "crib death," so some parents mistakenly believe that putting their baby to sleep on a bed, couch or bassinet will prevent it. This is a myth -- an approved crib is the safest place for a baby.

Even if baby falls asleep in the car seat or stroller, it’s best to transfer them to a crib (yes, even if you’re risking waking them up) if they’ll be asleep for a while. Because babies have poor head control, sleeping while sitting up might increase the risk of upper airway obstruction and oxygen desaturation.

Reducing your baby's risk of SIDS doesn’t have to cost money -- it's just about attention to details. Remember -- even though SIDS is rare, when it's your baby, you’ll want to do everything you can to prevent this from happening.
