We usually sit him in the high-chair without using the safety belt. That’s because he hates it and we normally do not leave him unattended.
In any case, the high chair belt can open unexpectedly in use, creating a fall hazard.
Parents, if you have been using this chair, please check if yours fall under the batch #17389 with production dates 0607-0911.
Come to think of it, we see a lot of places using this high-chair too, such as restaurants, cafes, etc.
