Katie (8 months) can easily roll over and is confident crawling around investigating her environment; however, she is unaware of other infants and toddlers in the room.

Sheis learning how to pull herself to a standing position and walk around furniture. When offered a walker or wheeled toy, she stands and begins to attempt to propel herself forward. Q:How do you know if the environment is providing the accurate amount of stimulation for Katie and the babies?
