Cognitive Activities for 18-24 Months Toddlers

From 18 to 24 months, your toddler's cognitive development is remarkable. They begin to engage in pretend play, solve simple puzzles, and can match objects to pictures. Their understanding of categories, sequences, and basic concepts like "big" and "little" is growing daily.
