Maybe watching her walk around would help. It would be even better if she wasn't make such a stressed out look too. While the blind girl couldn't see expressions, she knew that they played a vital role of communication to others. Songs chest puffed with glee, her legs getting a bit jumpy with excitement over figuring out a solution. Well it was more like the answer presented itself. After the brief excitement, the sand spider managed to calm down before starting to walk around a bit again. This time she was smiling. Each step was slower than before so he could observe the walking better, each leg at a different step in walking. In the end her biggest key to getting this done was having something none of his family had, eight legs. Having four legs on each side let the baby get a better example of how the legs move, even if Song herself was unsure how two legged people kept their balance. In a few hours, she had the child slowly wobbling along on his own two legs. This made watching the child a lot easier, since she could get him to walk places on his own now. There were meals, playtimes, and naps. The parents had arrived while their baby boy was slowly going after the pet cat, whom decided to jump to higher grounds and leave as soon as he got too close. The job was so easy that she almost felt bad for accepting the reward, almost. She knew it was probably that easy for her due to how used she was to being around kids much younger than her. It wasn't her first time seeing first steps, changing diapers, or getting a baby to nap.
