Sweet potato storage question

I sliced a sweet potato and steamed part of it for my baby and the rest I put in a plastic bag in the fridge vegetable drawer. I took the same one out today and used it in lentil soup. I didn’t realize It’s been 10 DAYS since I sliced it until halfway through..read you shouldn’t use sliced sweet potatoes after 3-5 days in the fridge. But it looked fine 🤷🏻‍♀️ now I’m thinking should I maybe not give the soup to the baby?
