What are the standard growth values that a 21-month-old baby should reach?
Answer
In normal development, a 21-month-old baby should be able to climb stairs while holding a railing, throw balls with purpose, pull toys forward and backward, stack 3 to 4 blocks, draw randomly on paper with a pencil, and pour small balls out of a bottle. In terms of language development, the baby should be able to recognize and point out body parts, understand about 50 words, and speak about 10 meaningful words. In social adaptation, the baby should be able to express the need for bathroom use, understand simple instructions from adults, and start learning to feed themselves with a spoon.
