Play in the snow if your toddler likes it. Make snowballs and see how far you can throw them. Make a snowman and dress him. Make snow angels.
Look for ice outside. Touch the ice and feel how it is cold. Hold some in your hand so your toddler can see it melt. Talk about how the cold turns water into ice.
Walk outside. Let your toddler experience firsthand the feelings and sights of winter. Explain how it is cold outside. Emphasize the need for coats, hats, mittens and boots when outside.
If there is snow on the ground, touch it and walk in it. Let your toddler feel how snow is different from the ground. Don’t be surprised if your toddler doesn’t like it and wants to go inside.
