Melissa & Doug Deluxe Chomp and Clack Alligator Wooden Push Toy and Activity Walker

Hold each of her hands (or have Dad hold one and you hold one) and just practice. Eventually she will feel more confident to try on her own. Also push toys. I don't think my kids would have learned how to walk without something like a little baby walker haha. This one was the best https://a.co/d/080emoGW

This is my favorite go-to, we own one and love it! My kids both used it (aff link) https://amzn.to/44f6suu
