I'm the worst mother ever😭 Pulse oximeter HELP 9M OLD

I feel super bad I just wanna crawl in my closet and hide. I didn't mean to! and didn't know this could happen! please don't trash me as I didn't know and I have cried for an hour...My 9 month old wears a pulse oximeter for her oxygen and heart rate while on oxygen. I must have place the brown sticker around her little toe to tight after her bath last night cause theres a small blister on her toe from it😭😭😭😭😭 I didn't mean to I sware! Lord I didn't mean to! Please forgive me it was an accident. My heart hurts cause of this. I would never hurt her😢. I change it every other day and have never had this problem until I put it on her toe for the first time. Is Children's neosporin or Aquaphor healing ok to put on it? I'm scared someone will see this and think I abused her and will call CPS or something! I'm a good mother I just made a mistake is all. I'm so upset! I'm nervous about putting the pulse ox back on anywhere now but she needs it. Mommys so sorry sweet girl.😔😫😭😭😭😭😭😭😭😭🤧🤧🤧
