## Knock Description
Knock-Knock! Who’s There? is an interactive family photo app for babies, toddlers, and their parents or caregivers to play, talk, and connect together.

Add your own photos to the houses throughout the app, then surprise and delight your child as familiar family members and friends appear from behind each door. Say their names, talk about relationships, compare familiar faces, and enjoy simple back-and-forth play together.

Knock-Knock! Who’s There? is designed to encourage interaction between parent and child — not just between child and device.

Together, children and their parents or caregivers can:

• Enjoy simple back-and-forth play  
• Recognize familiar family members and friends  
• Learn about different family and social relationships  
• Notice similarities and differences between people  
• Talk about names, faces, and familiar characteristics  
• Build connection through shared attention and conversation

Features include:

• Personalized play using your own family photos  
• Simple interactions designed for babies and toddlers  
• Familiar people appearing behind doors for surprise and recognition  
• A final interactive camera moment featuring your child  
• Touch, sounds, movement, shapes, colors, and visual textures  
• Easy-to-follow directions for parents and caregivers  
• Designed to encourage shared parent-child play  
• Based on developmental ideas about the importance of interactive play

Knock-Knock! Who’s There? is part of Two Way Play, a series of interactive experiences designed to encourage meaningful play between young children and the important people in their lives.

Two Way Play was created by Kim Foehl, MD, a psychiatrist and psychoanalyst experienced in working with children and parents.
