Is it normal for a 4yo to want an iPad??

My youngest keeps asking for "screen time" now because his older brothers get it. He's obsessed with watching Bluey clips on my phone. I feel like 4 is too young but also I'm exhausted and sometimes I just need 20 mins of peace lol. My older two turned out fine with screens... but this feels different? Anyone dealing with this yet? What's the move here?
