What causes knots in the umbilical cord?

Answer by  mary70 (101)

knots occur often when the cord is too long and the baby moves around and also in identical-twin pregnancies that share a single amniotic sac the cords may get tangled together also. As long as the cord stays loose it usually does not harm the baby. Keep an eye on it though

Knots in the umbilical cord are formed in the womb when the baby moves around. Another reason for umbilical knots forming is due to the fact that the cord is too long. Still, knots are known to occur in identical-twin pregnancies since identical twins share a single amniotic sac thus making it possible for the knots to become entangled.

Knots in the umbilical cord can be caused by the babies movement in the womb. Early in pregnancy the fetus has enough room in the womb to twist and turn.
