For the little ones, when it is all about color, sound and texture, you can easily make many different toys literally in minutes.
You will need a piece of fabric (length twice the width), some ribbons and some scrap fabrics to fill it. Additionally you can sew a bell inside or add a piece of a crinkly plastic bag for sound effects.
1. Fold the fabric in half (good side inside) and sew two sides together. You can already add some ribbons in this step.
2. Turn the fabric right side out. Fill it with some scrap pieces of soft fabric and add materials that make interesting sounds (experiment!). Close the remaining side by putting the two seams together to form a tetrahedron.
3. Add additional ribbons if you wish, and and sew the last seam to close the remaining oppened side.
For additional colors and textures, you can connect several different fabrics to form the rectangular piece you start with. This will also give you more seams to insert ribbons in. Have fun experimenting!
