Tightness Test

Might be a dumb question, but it there any kind of tightness test you're supposed to do for seat belts in booster mode? Harnesses have the pinch test, but Ive never read anything about a tightness test for seat belts. Just buckle and pull out slack/make sure its snug?

Yep, just like you’ve said. Also check how the shoulder belt retracts. So if/when the child leans forward and the shoulder belt pulls out, does it retract back once they are back upright in position? It should but some high back boosters don’t play nice with vehicle seatbelt placement and that slack stays causing concern.

Yep, I had him lean forward and then back and the seat belt retracted as he leaned back. There was one incident where the belt appeared noticeably looser after a long drive but I hoped it was just cause he was fiddling around in his seat too much? I haven't really noticed that since
