First trimester weeks

Congrats! During the first trimester, you’re getting used to the idea of being pregnant.

Second trimester weeks

As you enter this second trimester, your body will settle down to pregnancy.

Third trimester weeks

You've reached the third and final trimester and will be heavily pregnant by now.

Week 29 of Pregnancy

Use this third trimester to get organized before your baby is born.
You may feel a little bored and back-achy at this stage of pregnancy, but there are plenty of positive ways to take your mind off things. For example, you could start to make enquiries about breast-feeding classes, plan your maternity leave, and draw up shopping lists of baby essentials, such as diapers, a changing mat, onesies, bibs, and baby wipes, and perhaps buy a couple of items each week.

Your baby today

The sleep-wake cycle is now more established, however just because your baby is moving you cannot assume that he is awake. He spends little time fully active with his eyes open, so many of the movements you are feeling are happening while he is asleep.

Your baby's growth depends on many factors and its rate varies through the course of your pregnancy.

The growth of your baby relies on a steady stream of nutrients. Most nutrients are transferred unaltered across the placenta, but some substances are made by the placenta itself and a few are produced from scratch by your baby. These include the hormone thyroxine, the production of which depends on iodine from the mother crossing the placenta. Thyroxine has several functions and its level needs to be controlled very precisely. The placenta forms a nearly perfect barrier to thyroxine, enabling you and your baby to adjust thyroxine levels independently of each other. In the early stages of pregnancy, genetic factors largely determined the size of your baby, but by now environmental factors are becoming more important. Overall, your baby's final birthweight is determined about 40 percent by genetic factors and 60 percent by environmental factors. Your baby grows at a steady rate from 24 weeks until the last 2-3 weeks, when growth continues but more slowly. (If you're expecting twins, your babies grow as if alone in the uterus up until 28 weeks but from this point there is a reduction in their growth rate.) Your baby's internal organs account for much of his current growth. The liver and brain, in particular, continue to enlarge and muscle mass increases. Later, fat will be deposited under the skin, rounding out your baby's contours.

Focus On... Twins

Buying for your twins

The clothes you buy for your twins should be easy to put on and take off, and, of course, machine washable. You'll probably be given outfits as presents, so just buy the basics.

For each baby, you're likely to need at least:

  • Six undershirts
  • Six onesies
  • Two jackets
  • One or two hats (sun hat for summer)
  • Several burp cloths and bibs.

Keep in mind when choosing diapers that twins are often smaller on arrival than a single baby, and you may therefore get through a wide range of sizes in the first few months.

It's advisable to buy a good-quality double stroller, since it will be used for quite a while. When choosing a stroller, a side-by-side model is preferable to a tandem stroller, so that your babies can see each other and communicate as they grow older.

As A Matter Of Fact

The number of twin births has been jumped 66 percent from 1980 to 2003.

The number of triplet births or more increased four-fold in the same time period. Twins are born, on average, 17 minutes apart.
