A baby in the 6-12 month age range is engaging more through laughing, babbling, sitting, rolling, crawling, pulling to stand at furniture, and may be very close to taking his or her first steps! Age-appropriate toys for babies at this age include cause-and-effect toys, which are often battery-operated toys that play music or complete fun actions with the push of a button. Babies at this age also start dump-and-fill play, putting large toys in and out of containers.
