Week Twenty Nine: Movement is more forceful
You are 29 weeks pregnant. (fetal age 27 weeks)
- Your baby now weighs about 2 and a half pounds (1150gm)
- and is about 15 inches (38.5cm) long from head to heel.
- Brain is busy developing billions of neurons.
- Baby’s muscles and lungs are continuing to mature.
- The fetus can taste and respond to pain.
- The milk teeth have developed under the gums.
The baby’s head is growing bigger to accommodate the brain, which is busy developing billions of neurons. The eyes can move in their sockets. They may be able to follow a blinking light. As well as your baby’s increasing sensitivity to changes in light, they may also be able to taste. Various studies show that your baby may indicate preferences or dislike for particular tastes at this stage.
Baby is also moving from side to side, but probably still is head up. In the next few weeks, they will move to the head down birthing position. At times you may feel as if baby is performing somersaults for an olympic gold medal. Baby may be performing fewer movements because living conditions in the womb are becoming more cramped. The baby is still doing a lot of kicking and stretching. Some of your baby’s kicks and punches may even take your breath away.
Baby hears things better from the vibrations all around, and can now distinguish real sounds and voices. Do not forget to continue to ‘teach’ your baby in the womb by exposing them to music, literature, and simply talking to them. At this stage baby eyes are almost always blue and can distinguish bright sunlight or artificial light through the uterine wall.
At week twenty nine, your baby measures about 11 inches (28 cm) from crown to rump, or a total length of about 15 inches (38cm) from head to heel, and weighs about 2.5 pounds (1150gm).
Your baby is still in the midst of a period of intense activity. The blood vessels in his lungs are maturing and they’re gradually getting ready for his first breath. For now your placenta is providing him with all the oxygen he needs.
All five of your baby’s senses are developing well (sight is the last to develop and will continue maturing once he’s born). He’s increasingly sensitive to changes in light, sound, taste and smell and may indicate preferences for particular tastes or odors. Whatever you are eating will flavor your amniotic fluid. It can smell strongly of curry, garlic, onion and cumin for example, and researchers have found your baby will drink it faster the sweeter it tastes (one study showed that a 33-week premature baby will suck harder on a sweetened nipple than on a plain one).
Your baby now weighs about 2 1/2 pounds (like a butternut squash) and is a tad over 15 inches long from head to heel. His muscles and lungs are continuing to mature, and his head is growing bigger to make room for his developing brain. To meet his increasing nutritional demands, you’ll need plenty of protein, vitamins C, folic acid, and iron. And because his bones are soaking up lots of calcium, be sure to drink your milk (or find another good source of calcium, such as cheese, yogurt, or enriched orange juice). This trimester, about 250 milligrams of calcium are deposited in your baby’s hardening skeleton each day.
Baby’s now the size of a squash!
Baby’s energy is surging, thanks to white fat depositing beneath his skin. And since he’s growing so fast (weight will triple by birth), things are getting kind of cramped in the womb. What all this means for you: Get ready for some more kicks and jabs to the ribs.
