Winfun Giggle and Learn Electronic Shape Sorter. This is not your average shape sorter, it's complete with Fun Sounds and Melodies. When Your Little one puts the Correct Shape into the Hole, they will See Lights and Hear Sound Effects. At this age, babies are still heavily dependent on their parents. It is also a period of rapid growth and development – babies start to make their first meaningful sounds and learn to crawl and walk. During this phase, babies can sit up unaided; by twelve months, they can stand and start to learn how to walk. This is the perfect addition to your playroom for any child 6 Months and Up.
