A woman who is 26 weeks pregnant is six months and two weeks pregnant. The 26th week is at the very end of the second trimester, according to Baby 2 See.
At this stage in a pregnancy, the baby's hearing is fully developed and he begins to react to sounds. The baby is sleeping and waking regularly, and the patterns of his brain waves are equivalent to a newborn's. At 26 weeks, the lungs have begun to develop but are not yet fully grown. The mother should be able to feel the baby regularly moving inside of her and can expect to continue to gain weight at a rate of around 1 pound per week, according to WebMD.
