The development of young children in the first 24 months of life is extremely interesting with many surprising changes, both physically, emotionally and cognitively. Parents need to closely monitor the growth of young children, and pay attention to their nutrition so that their children can develop most comprehensively.

A prominent feature of 21-month-old children is that they are easily upset or cry. They are also easily distracted during meals. Children at this age love to imitate their mother's actions. Mothers should grasp their child's developmental milestones to help them develop better.
