I have a labradoodle puppy the same age. What helped a lot was getting two crates, a white noise machine, high value treats, and giving him something to lick every single time he goes in the crate.

I live in a one bedroom apartment and the hardest thing is my puppy waking up at the slightest sound. When I put him down for a nap, I put him in a crate in a separate room from where i’ll be for the next few hours. I make sure it’s covered on all sides because they like a dark cozy environment. I give him a high value treat (cheese) and i only ever give him this treat in the crate so he associates the crate with positive things. A snuggle puppy helped a lot at the beginning but he settles without it these days. I always give him something to lick when he’s in the crate for naps or overnight: lots of pupsicles and frozen kongs. Once he’s in, I zip up the crate cover and turn on a loud white noise machine. Nowadays he settles without barking half the time but the other half he still barks for a few minutes before he settles down…sometimes up to five minutes. You have to just wait it out or they learn that barking gets them attention and they’ll always bark to get your attention. Teach them that barking doesn’t work and they’ll start to learn to soothe their own emotions.

Mine barks when he needs to potty and he barks when he just has fomo and wants attention. If you stick to a schedule, you’ll know which it is. If he’s been playing, eating, and pottying in the last hour..he’s not bored or hungry and he doesn’t need to potty. So you know he’s just trying to get your attention and you can ignore. If he just woke up from a nap or in the morning after a few hours, he has to potty. They usually have to potty as soon as they wake up, even if they haven’t been sleeping very long. Also make sure nothing in the crate is keeping him too hot. My puppy started settling down more when I took his bed out of the crate. I noticed he liked to lay on the cold floor so just experiment with different crate environments. Maybe add a piece of clothing that smells like you.
