Good, so we know he responds well to honey. As I mentioned before, the honey effect will expire soon. So, keep testing!
He might start bouncing, i.e. going up and up. If that happens you can test less often.
If it is only the honey keeping him up, his number might start going down again since it is still early in the cycle, but know you know what to do

As Bandit's mum said, once you feel more confortable with green numbers (and get to know Milo's paetterns an responses) you may try to keep him up just with the gravy lover's and reserve the honey for when he hits 3. But I know when I started, I hit the honey all the time....
