IMHO, if he is only going to be in there for a couple minutes (that is all I am allowed to do per regulation
, one minute per year of age) then no toys would be required.
My fear is that by his getting toys while he is "losing privileges" it may draw the problem out longer.
He gets his own space, own toys AND your attention by acting out... YKWIM?
I have also tried this technique, at a parent request, with a DCK 2 years of age.
My DCK simply rocked it back and forth to knock it over, climbed right back out or tried to bite/tear the mesh and destroy the pack-n-play.
Do you have a solid high chair to try instead? It may be less of a financial risk.
Just a suggestion from experience.
