I was going to stagger it. Do 5 week 12 or 13. Do 5 week 14 or 15. Do 5 week 16. Then I'll have everyone taste test them to see what age they like best.
I was thinking about trying this, but I only have 3 boys to process this time. The next batch will be 6 so I decided to try it then, 2 at a time. Plus those are all the same mix so would be a fairer comparison.
