Introducing peanuts( peanut butter)

My baby is 6 months almost 7. I’ve been introducing foods for the past 3 -4 weeks . So far he has an oat allergy and a cows milk protein allergy. I’m super nervous about introducing peanuts as I know it’s a high risk allergen and it’s usually alot of times a severe one. Do anyone have any tips on how to introduce this? What’s the best way to do so. I’m so nervous about it.
