Baby climbs out of tripp trapp, can I attach harness when baby set still in use?

[Cutestbaby]

Can someone please let me know if it is possible to attach stokke harness when baby set is still in use? I googled videos but what is coming up unfortunately does not explain how to do it.

My little one started climbing out during meal times on the tray or a table when tray is removed. But only 9 month so still using baby set and. My brain can't comprehend how to attach the harness...

I lowered the foot bar in hope that LO won't be able to push off it, but there seems to be a different escape technique in place.

Yep, you can. I have done it. The harness isn't brilliant (a bit fiddly to fasten and adjust) but has contained my little escape artist so far!

You attach plastic eyelets to the seat. The harness clips onto those. Hopefully you can see in the photo. My babyset is still on - the harness isn't actually attached to it at all.

The harness is the only thing I don't like about the chair...
