Sleep regression….maybe?

We have a 5 month old miniature schnauzer. He has slept in our crate since we got him at 8 weeks. Goes in around 10:30 and would sleep until 6:30-7. 2 nights ago he was up at 5, barking, I ignored until 6am then got him up. I thought maybe he had to poop or something since he wouldn’t settle back down. He didn’t, just short pee. So he tricked me. Tonight it was 4am he was up. I ignored him, 4:30 he puked so I got him up, changed his blanket, got him water and took him for a pee. Then it was straight back into the crate. It is now 6:15am and he’s still going 🥲 he stops for a few minutes and starts again. Do I just need to wait this out? Is this typical for this age? Any tricks that worked for anyone? He’s in our room, blanket over the crate with a sound machine. I’m so sleepy 😭
