Has anyone had a baby/toddler have surgery?

My 18 month old will be having surgery next week to remove a dermoid cyst off her scalp and i am TERRIFIED . Anyone have stories good of good outcomes? please help me with my anxiety I am so afraid at the moment. Her doctor said it's an easy direct outpatient surgery and will be done within 45 minutes but dear God I can't help but worry! I tried for this baby for 5 years! I am so scared of anything happening to her. She is my everything 😭
