It's maddening how much advice given to parents throughout the years has not just been a bit lame, it's been actively harmful.
Example: Food allergies.
For years, parents have been warned not to feed babies peanuts and such things until they were 3 years old. And only milk/formula until 6 months old.
When they finally get around to doing randomized trials, it turns out the best way to PREVENT food allergies is to feed babies exciting things at 4 months.
4 months!
Maddening. #dadtoot
