Fraternal twins conceived when two eggs are released by the ovaries and fertilized by each different sperm. They share the same space in the womb. Identical twins are conceived when the sperm fertilize a single egg cell and the resulting zygote splits into two separate parts, each with the same genetic makeup.A twin pregnancies are usually only about 37 weeks, shorter than single births. Twins would have lungs like an adult at birth, but will likely be smaller and lighter weight than a single baby.Early Stages of Multiple PregnanciesMost parents know their baby twins carrying twins of routine ultrasound done between weeks 16 and 20.During the first two trimesters of pregnancy,twins develop at the same rate with a single baby. At week 6, respectively twins expand about 1/10 of an inch long, or about the size of a grain of rice. In the 5th month, expands twins 7-10 inches, the size of a large banana, weighing about 1 pound each baby.Last Trimester Pregnancy Baby TwinsIn the third trimester of pregnancy with twins, a typical growth pattern and is different from a single pregnancy.

Babies born at this stage will probably spend at least three months in intensive care units. One third of them will survive without health problems.At 28 weeks, viability increased drastically. Nearly all infants (99 percent) who get to this stage survive, but some suffer complications.Infants born at 32-34 weeks have a good chance of survival without long-term complications. If their lungs are not fully developed, the baby may need to spend time tercsebut ICU or may require oxygen tanks to survive.
