That's not a dumb question.
I always did 30 min. from the start of the milk feed.
However, my lo downed every bottle in 5 minutes LOL
You just don't want it too close to the next feed...you want it closer to the feed they just had.
Some lo's like to have it right after the bottle/bf so it's really up to what your baby needs
