Bluey isn't a preschool cartoon that focuses on kids, it's a preschool cartoon that focuses on both the kid and parents. We see the parents having genuine fun with their kids through playtime as in simple games. The family would play freeze tag, pretend, and keeping the balloon off the floor. The show doesn't teach kids any life lessons, it's actually teaching the parents many life lessons like taking some time off to have fun your child. Even adults without kids can still like it because the show factors in nostalgia. It's new but the various moments in the show felt like memories of when you were a kid having fun. It reminds you of a bygone era, but that era can be made for your own kid. It also handles some heavy topics in a way that kids understands. Apparently there was an episode where Bluey aunt came in to visit, and Bluey wondered why her aunt love kids but seems to never have kids of her own. Well the aunt is sterile, so she can't never have any kid of her own, and you can actually see her struggling with it. There's another episode where Bluey and her sister are playing a game called evolution where they act like different stages of life like fish to anthropomorphic dogs. But this completely change to where Bluey is acting like a mom to her sister, Bingo, and she witnessing Bingo pretend growing up. Bluey is experiencing a perspective of a parent where they see their child grow and be proud of them before passing away and going to heaven. That's some deep philosophical stuff right there for a show that encourage playtime.
