Q

Hand preference before 12 months?

A

Hand preference (or handedness) in infants typically does not become apparent before 12 months of age. In most children, clear hand preference develops gradually between 18 to 24 months and becomes firmly established by about 3 to 4 years.

Before 12 months, infants should use both hands equally for reaching, grasping, and exploring their environment.

*Abnormal: Neurological deficit (Cerebral Palsy) or other motor problems.

Q

Umbilical embryology?

A

During development the umbilicus has two umbilical arteries and one umbilical vein. The arteries are continuous with the internal iliac arteries and the vein is continuous with the falciform ligament (ductus venosus). After birth, the cord dessicates and separates and the umbilical ring closes.
