Answer :
Hopping on either foot is a developmental milestone typically achieved by children at around 48 months old, indicating effective muscle coordination and balance (option C).
The developmental milestone of hopping on either foot is usually achieved by 50-90% of children by the age of 48 months (4 years old). This means that the correct answer to the question is option C. 48 months. This motor skill is significant because it indicates good muscle strength, coordination, and balance.
It fits into a series of milestones, such as being able to sit alone at 7 months on average, and most babies being able to hold their head up at 6 weeks old. By the age of four, children can typically grip a crayon with a tripod grasp, as well as perform tasks such as skipping on alternate feet and balancing on one foot, which suggests the appropriate age range for hopping on either foot. Delays in achieving these milestones are often cause for concern and indicate a need for further assessment by a pediatrician.
