Cognitive Activities for 9-12 Months Babies

Between 9 and 12 months, your baby is becoming a little problem-solver. They can imitate simple actions, find hidden objects, and start to understand how objects relate to each other. Their memory is growing stronger and they love repeating activities that give predictable results.
