Two-year-olds are experiencing rapid development in physical abilities, language, cognitive skills, and emotional awareness while asserting their growing independence. During this stage, children develop better coordination, begin forming simple sentences, engage in pretend play, and experience intense emotions they don't yet have the tools to fully regulate. Their desire for autonomy often leads to testing boundaries and occasional tantrums, which are normal expressions of their developing sense of self rather than acts of defiance. Supporting a two-year-old involves providing opportunities for exploration and independence, acknowledging their emotions, maintaining consistent boundaries, and understanding that their development follows individual timelines.
