I wonder why the old advice was being given if it was so wrong? If nobody understood what to do, shouldn't there have been no advice instead of something harmful?

There were numerous studies that associated early exposure to peanuts with increased risk of peanut allergies, because that is much cheaper and easier and easier to justify ethically than random assignment trials. And for skin exposure via peanut oil, they were absolutely correct.

For example: https://www.nejm.org/doi/full/10.1056/NEJMoa013536 https://d1wqtxts1xzle7.cloudfront.net/74207249/j.1399-3038.1...

It is also the case that after sensitization, avoiding the food can lead to eventual desensitization (although it is riskier in the meantime), which was interpolated to support avoidance: https://onlinelibrary.wiley.com/doi/abs/10.1002/j.1536-4801....
