I'm no expert mom, but now that I've had a few weeks of using the baby products I purchased I wanted to share what I've loved!
Sleep

Muslin crib sheets are so soft and form to the crib super well so you don't have to worry about extra fabric bunching up!

We got the Newton crib mattress, maybe it was the marketing but I do like the fact that we can wash the outside and rinse the inside if needed and the baby likes to sleep on it so it is worth it to me!

The Graco Sense 2 Snooze is a dupe for the Snoo and to be honest, I'm not sure if we would've needed a smart bassinet because our boy started as a pretty good sleeper to begin with, but I do enjoy all of the features of this bassinet. If you have a bad sleeper or are worried about having a bad sleeper like I was then this is a good choice!

These bassinet sheets are great! Super soft and hold up in the wash.
There are a few swaddles that Teddy likes. My best recommendation is to get the sample pack from babylist so that you can try out the ones that you and your baby like. Our sample pack included some of the swaddles that he has loved!

Halo swaddle is his favorite and was also used at the hospital, they had a cheaper version with no velcro and snaps that they had for us (which was so nice) and they also gave us a nice version like this with the Velcro and zipper when we were discharged. I was glad that he's liked it because we were gifted a few of these and they also included one with the babylist swaddle sample pack.

The SwaddleMe was also included in our sample pack and we they sell a similar Disney version at Target that is slightly different. This one is great the one from Target fits differently somehow so we don't love it as much.

The ErgoPouch is the last swaddle that Teddy loves and if he was a worse sleeper I would've bought more of them... anything to help a baby sleep!

The Hubble Connect baby monitor is great because it can be connected to the internet if you want to be able to view your baby from your phone or you can leave it off of the wifi and use the monitor only. There's two cameras so you can see the whole room and have a close-up view of your baby in the crib. The monitor has a ton of other features like two-way talking, saved music, and a ton of other things that we don't use but you might!

We use our Hatch in our room religiously so I knew I would get one for Teddy's room and it's been great. We got the Rest+ 2nd Gen so that we could use it off of the base and that it would work if the power went out.

If you haven't heard of the heating pad trick to help your baby go to/stay asleep when you put them down, it's really simple. 15-20 minutes before you plan to put your baby down put a heating pad down in the crib/bassinet on low and have it warm up the space to mimic your warmth and help them stay asleep. We actually keep one by the bassinet in our room and one by the crib in his room.
This is just what all three of us love for now, we'll see how it changes as he gets older and his sleep need evolve.
