That's a tough question. She is very young but you want to encourage her curiosity. Can you find her a toy sewing machine to encourage her but not put her in danger? At her age, instead of getting a poke in the finger like us big girls, it could really damage her tiny fingers. Let her help you pick out fabric and hold her in your lap as you sew. If she can control the pedal, put the pedal on a stool and let her press it when you sew. I love that she is interested and that you are doing your best to encourage her. Best wishes to both of you!!!
