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.

Is having a big baby hereditary?

Is it true that if you were a big baby at birth, your babies will be big too?


Is it true that if you were a big baby at birth, your babies will be big too?

The Bump Expert

Yep, it can be. In general, babies tend to be in the same weight range as their parents. In other words, if you were nine pounds, eight ounces at birth, it’s incredibly unlikely that you’ll give birth to a five-and-a-half-pound peanut. Of course, there are other factors that can affect baby’s birth weight, though, including:

• Birth order. Younger siblings tend to be larger than their older brothers/sisters.

• The baby’s sex. Newborn baby boys typically weigh more at birth than girls.

• Your weight. Heavier moms are more likely to give birth to larger babies.

• Your pregnancy weight gain. The more weight you gain during your pregnancy, the more likely you are to have a bigger-than-average baby.

• A history of diabetes or gestational diabetes. High blood sugars can cause the baby to gain weight. That’s why it’s so important to keep your blood sugars under control during pregnancy.

• A history of large babies. If your last two babies were both eight pounds-plus at birth, you’ll probably have another eight-pounder (or so).

Don’t freak out, though, if you were a “big baby.” Women’s bodies are designed to give birth, and odds are, you and your baby will do just fine.

Is having a big baby hereditary?

Both my husband and I were smaller babies and my daughter was a whopping nine pounds. So we will see if this little guy follows suit and is on the large side.

Is having a big baby hereditary?

Soon to be first time mom here, I was 10 pounds and all 3 of my siblings ranged between 7-9 pounds at birth. My boyfriend was 7 pounds and a twin! 26 weeks pregnant now and I can see her being a whooper! scared because I am on 23 years old, very narrow, and before pregnancy weighed 115 pounds and I am 5'4! eeekk!

Is having a big baby hereditary?

Don't worry CoreW12. I am also petite (5'3" and 118 before pregnancy) and I gave birth to an 8lb, 12 oz baby girl! She was my first as well. I breast fed and within a year after delivery I weighed less than before I got pregnant. I'm pregnant with baby girl two now and am expecting one the same size or bigger in just 8 weeks! It's funny that little women sometimes have big babies!

Is having a big baby hereditary?

This is slightly terrifying. My husband was 1 month premature and 10 lbs, and every boy in his entire family has been 10+ lbs! My daughter was only 7 lbs 3 oz and they kept saying she was going to be huge. Now I am having a boy and I am scared about being ripped V to A...
