Human babies can typically stand while holding onto furniture or a hand
between 6 and 10 months and stand independently for several seconds
between 11 and 14 months.
This bird seems to have very good balance despite the child's arm movement.
The bird also has the balance and coordination to lift one claw. The typical baby
does not have the balance to stand on one foot until between 16-17 months.
The child's arm appears to function as a balance beam. Toddlers can typically
walk across an eight inch beam between 17 1/2 and 19 1/2 months and across
a four inch wide beam between 3.2 and 3. years.
