Maternity clothing sizes work the same way as regular ones do, meaning, you're the same size in maternity clothes that you are in regular clothes. If you normally wear a size small, you'll be a maternity small, too. It's the same for numbered sizes: a regular 6 or 28 is equivalent to a maternity 6 or 28.
Most pregnant women gain between 10kg and 12.5kg (22lb to 28lb), putting on most of the weight after week 20. Much of the extra weight is due to your baby growing, but your body will also be storing fat, ready to make breast milk after your baby is born.
During pregnancy, the lining of your uterus thickens and its blood vessels enlarge to provide nourishment to the fetus. As pregnancy progresses, your uterus expands to make room for the fetus. By the time your baby is born, your uterus will have expanded to many times its normal size.
In the second trimester (weeks 13 to 27) , your breasts will get larger and heavier. You may need a larger bra that gives you more support. You will probably feel less of the tenderness and tingling from early pregnancy. As your breasts grow, the veins become more noticeable under the skin.
- For maternity clothing we recommend staying with your pre-pregnancy size. As all pregnancies are unique and individual, maternity clothes are designed on a normal pregnancy weight gain range. Although it can be tempting to order a size up, only do so if you prefer a relaxed fit or if you have a very large bust.
The average weight of a baby born at 37–40 weeks ranges from 5 lb 8 oz to 8 lb 13 oz. This is 2.5 to 4 kg. At delivery, experts consider a low birth weight to be less than 5 lb 8 oz, or 2.5 kg. It is common for babies to lose around 10% of their weight shortly after birth.
More than 9 out of 10 babies born at term (37 to 40 weeks) weigh between 2.5kg and 4.5kg. If your baby weighs 4.5kg or more at birth, they are considered larger than normal.
About 10-15 days after birth, you start making mature milk. Like each phase of breast milk, it has all the nutrients your baby needs. The amount of fat in mature milk changes as you feed your baby.
Your breasts may or may not return to their pre-breastfeeding size or shape. Some women's breasts stay large, and others shrink. But sagging or staying full can be as much a result of genetics, weight gain during pregnancy, and age as a result of breastfeeding.
Milk production generally begins around the midpoint of pregnancy, somewhere between weeks 16 and 22. At this stage your body is producing what's known as colostrum—a yellowish milk that's rich in calories and disease-fighting antibodies—which will serve as baby's first food after birth.
Your little one will get a whole lot larger in the third trimester, growing from about 2 1/2 pounds and 16 inches long in week 28 of pregnancy to between 6 and 9 pounds and 19 to 22 inches long in week 40.

Pregnancy hormones drive this unique pattern of fat accrual. Even worse news? For the average pregnant woman, a fifth or more of the fat she gains goes to her upper thighs.
If ultrasound exams during pregnancy show that your baby is very large, your healthcare provider may recommend early delivery. You may need a planned cesarean section. After birth, a baby who is large for gestational age will be carefully checked for any injuries that happened during birth.
A history of breastfeeding, the number of children breastfed, the duration of each child's breastfeeding, or the amount of weight gained during pregnancy did not predict changes in breast shape—dispelling the myth that breastfeeding causes breasts to sag.
If you have a normal, healthy pregnancy, then pumping before birth is often completely safe. If you have a high-risk pregnancy, it may be better to play it safe. As you begin to experience physical changes during your pregnancy, you may notice that your breasts leak small amounts of colostrum.
Air-dry your nipples or dab them gently with a towel. Women used to be told to rub their nipples to toughen them up, but this isn't advised any more – thank goodness! There's no need to clean the breast or nipples before breastfeeding.
Lactation begins as early as a few weeks into the second trimester of your pregnancy. As estrogen and progesterone levels rise, your body prepares for lactation by increasing the number of milk ducts in your breasts, and those milk ducts will transport milk from the alveoli to your nipples.
A larger than expected fundal height could be a sign of fetal macrosomia. Excessive amniotic fluid (polyhydramnios). Having too much amniotic fluid — the fluid that surrounds and protects a baby during pregnancy — might be a sign that your baby is larger than average.
Most women lose around 13 pounds (6 kg) right after childbirth, which includes the baby's weight, as well as the weight of the amniotic fluid and placenta. When it comes to fat loss, with a healthy diet and regular exercise, you may lose about 1 pound (0.5 kg) a week.
