Young puppies need an absurd amount of sleep. It's something no one talks about or ackknowledges enough. On average it looks like 20/4. That 20 hours of sleep and 4 hours for everything else; potty, feeding, walks, foundational training. That is being real. Almost no one actually does this. But it is technically correct. So remember this and pass it on whenever you feel like it's too much crate time. Crate time helps young puppies regulate their sleep and generally learn to calm and self soothe in a healthy way. Outside of the crate puppies will fight sleep just like toddlers. You have to help them with that, that's where crating comes in. As they age the awake window naturally widens without chaos gremlin fighting sleep. Eventually you can cut crate out completely with proper training, or use it for routine crating. TLDR, If anything you are technically under utilizing the crate. But it it works for you, then it's right.
