Answer:
16 months
Explanation:
According to my research on child development norms, I can say that based on the information provided within the question babies often walk alone easily by the age of 16 months. Studies have shown that on average babies begin to learn how to walk between 9-12 months of age but during this period they tend to stumble a lot. Between the ages of 14-15 months of age babies begin to learn how to walk effectively without stumbling and are walking easily by the time they are 16 months old.
