Your skin lets you feel things. Touch tells you if something is soft or hard, warm or cold, smooth or rough, or even sharp.
Think of your skin like a feeling blanket. With touch you can tell if a toy is squishy, stiff, warm, chilly, bumpy, or pointy.
Your skin sends messages to your brain when you touch something. That helps you know if it is soft, hard, hot, cold, scratchy, or pokey.
