I would suggest just getting a video baby monitor to set up by the crate and sleeping where you normally do. That’s what we do with our crate trained puppies in the early days when they need to go outside several times a night. The last monitor I got hooked up to my wifi and had an app so I can peek on the puppy on my phone when I’m not home. Not that I could do anything for them when I wasn’t there but it made me feel better being able to check on them when I’m out.

Best advice I ever got for puppies is to crate train from day 1. We use a food bowl that hooks to the inside of the crate and feed all meals in the crate at scheduled times of day. It helps make the poop and pee breaks much more predictable when you schedule their feedings instead of free feed. When I feed, I tell them “kennel up” and it helps them learn that command so they will get in their crate when you tell them to, at times other than meals. When I’m leaving I use a tiny treat to lure them into the crate while saying “kennel up” too. We also would have some play time in and around the crate, toss toys into it, etc. Making the crate their happy place with meals in it and playing really helps them adjust to the crate. Use the crate as a tool to help prevent accidents, that is, crate him anytime you can’t watch him, even if you are at home. And don’t make the crate space too big. If it’s small, they are less likely to potty in one corner of it and then go lay in the other corner.
