Sure, you can, but most parents don't say no every time, and that means sometimes asking's going to pay off.
Some of the "kidfluencer" content out there is clearly aimed at giving kids talking points to bring to their parents. Before we banned YouTube from the house a few years back, I had a couple experiences where my kids would come and give me canned marketing copy - "it's fun and educational for the whole family!" sort of nonsense - they'd clearly cribbed off a video.
