To sign door, take both hands and hold them up flat facing out, fingers together, so that you are looking at the back of them. Take one hand and fold it out so that it looks like a door opening.
A great way to teach door is to have someone knock on the other side and say something like," Let's go open the door!" This way, your baby can connect door with open.
The sign for door is easy to learn due to consistent visual feedback. Teach it as soon as your baby shows interest in going outdoors.
