Physical: Baby is able to “rake” food from highchair tray or bowl. As the term implies, this action involves baby dragging the open fingers of one hand across a surface. This is a precursor to picking up food using the “pincer” grasp.
Cognitive: Baby can distinguish emotion by the tone of an adult’s voice. Baby begins vocalizing first sounds, which include Ba-Ba, Ma-Ma and Da-Da.
Social/Emotional: Stranger anxiety has really set in. Even close relatives such as Grandma and Grandpa, can be perceived as strangers to a baby this age. Don’t worry, it won’t last long.
