28 weeks

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.
Your baby measures about 11 inches (28 cm) from crown to rump, or a total length of about 16 inches (38cm) from head to heel, and weighs about 2.5 pounds (1150gm). (or in our case likely much more :))
He's the size of a squash or a 16 inch tire. Oh baby!
