“Bad” gives toddlers a word for things they dislike before tantrums do the talking. It starts at the chin like “good” but flips away, and most toddlers pick it up between 12 and 18 months.

- Make the handshape: Hold your hand flat, fingers together, palm facing you.
- Touch your chin: Place your fingertips on your chin.
- Flip it away: Rotate the hand down and outward so it ends palm-down, pushed away from you.
The flip is the meaning: “good” lands gently in your palm, “bad” gets tossed away.

When to Use It With Your Child
- About taste: Pucker dramatically at a lemon and sign “bad” — toddlers love the theater.
- At safety moments: “Touching the oven is bad” — sign it calmly with the warning.
- In stories: Label the misbehaving character; pretend contexts are low-stakes practice.
Tips for Success
- Keep your face matter-of-fact — the sign carries the message without scolding energy.
- Expect “good” and “bad” to be confused at first; exaggerate the ending position.
- Use it for things, not the child — “that is bad,” never “you are bad.”
Signs Related to “Bad”
“Good” is the mirror sign that lands in the palm, and “don’t like” (fingers flicked away from the chest) covers preferences. Teaching “good” and “bad” together makes the contrast obvious.
The good/bad pair is one of the oldest documented contrasts in ASL, appearing in dictionaries going back to the early 1900s.
