Nine-month-olds are increasingly mobile, communicative, and socially sophisticated. They understand simple words and commands, wave bye-bye, and point to share interest. Pincer grasp is refining and self-feeding is becoming more efficient. This is also when stranger anxiety and separation anxiety are commonly at their peak.
