An 11-month-old infant is developing gross motor skills like standing with support and walking while holding furniture. Fine motor skills are improving as the infant explores toys, removes covers, and takes toys in and out of containers. The infant is beginning to hold crayons and make marks. Language development includes responding to questions by pointing and imitating speech sounds. Play stimulation suggestions include placing small objects in containers, rolling balls back and forth, and using a walker to practice letting go while grasping toys.
