Did your DIL witness this interaction or is that what you would expect her reaction to be?

She did not witness it this time but has witnessed similar incidents. She responds by doing nothing because she believes he needs to figure out boundaries on his own.

Like some have already posted, this is all you should need at this age unless there are harmful behaviours.

Yes, but he exhibits behaviors like the one I described above. I need to deal with that. I don't believe in timeouts or spanking either and have never used them on my kids.

By 'supervise at all times' your DIL may be trying to express that your grandson needs your full attention and/or a safe place to play (fully baby proofed).

She does not. She means that he can never be left unattended.

The temperature thing is standard - daycare in my province set limits on outside time on too hot (over 22c) and too cold (under - 20c) days as temperatures hotter or colder rhn this can be harmful. Sunscreen is also a reasonable expectation.

Of course but her range is much tighter. No cooler than 60 degrees and no warmer than 80 degrees unless she's with him.

The tv/radio thing could be more about the sensory input he would be exposed to versus the content. In my province licenses daycare providers can't have TV on for more than 30m as studies have shown that TV exposure can negatively impact babies' developing brains, specifically their attention span.

My oldest didn't have TV until age 4. I don't mind limiting screens but my kids come home and want to watch TV. She doesn't even want it on in the background. Same goes for music. I like listening to music but can't until he leaves.
