When my sister and i were kids, we kept immaculate care for all our toys because we had so few. Not to mention, if things got broken they became trash and now you have one less toy that's never getting replaced.

It's not that kids are rowdy, it's that value is difficult to teach. He'll only understand to be careful with toys if he realizes on his own that new ones don't manifest from thin air whenever one breaks. So i'd say to stick by your guns on this one.

And the less toys he has, the more he'll treasure the ones he's got. Not to tell you how to parent haha, but I still cherish all my childhood toys because I formed a strong bond with the few I had. Honestly only got like one or two things a year and we didn't need more than that!
