This category includes all the various tech products you’ll need for your little one. Monitors are in this category and have the widest spectrum of options. The rest of the items don’t get too complicated.
You indicated that you want a WiFi enabled video and audio monitor. I've given you two recommendations for baby monitors that have great video quality. Another alternative parents do is get an indoor camera that is integrated with their entire home monitoring system like a Google Nest. The tradeoff is that cameras like these don't offer all the features that are unique to baby monitors. Let me know if this is something you might be interested in and I can help you choose.
Nanit Pro Smart Baby Monitor & Wall Mount ($299.99): Nanit is one of the best baby monitors on the market. Aside from having high quality video and audio, it also provides a quick timelapse of the night, tracks sleep analytics and offers sleep coaching. Since you're not interested in tracking vitals, I'd recommend just getting the camera and wall mount. You can skip the Breathing Wear.
Lumi by Pampers ($229.99): If you don't need the sleep tracking but still want a high quality camera, you can save a little by going with the Lumi. This monitor was created by Logitech and offers a 1080p, HD resolution, and 180 degree ultra-wide views. It also has it's own sleep tracking bundle (sold separately) that you can skip. If you decide you want sleep tracking, I'd recommend the Nanit.
COOL MIST HUMIDIFIER
Cool Mist Humidifiers are great when your little one has mucus build up around their eyes (which is common in the early months) or congestion when they’re sick. Cool mist is an important safety feature, so your LO won’t accidentally burn themselves when getting too close. Since this is a pretty staple product, you can find great options around ~$40. If you want more advanced kinds that also serve as air purifiers, then you’re looking closer to ~$100+. My biggest recommendation is to go with one that has a large water capacity (1 gallon or more) so you don’t have to refill it frequently and is easy to clean.
Crane 4-in-1 Drop Ultrasonic Cool Mist Humidifier ($54.99): This humidifier has the basics you need - 1 gallon tank, easy to clean, super quiet, and a spout that can rotate so you can direct the cool mist to any part of the room. It's filterless, meaning you don't need to buy replacement filters every month. It also comes in a variety of colors to match with any nursery decor. You might come across a couple of different versions of this humidifier, I chose this option because it has a top fill water tank (super convenient).
LEVOIT Humidifier 6L ($89.99): I added this option because you mentioned your home is larger and this humidifier is made for large spaces (up to 700 sqft vs. 500 with the Crane). While it is on the pricier side, there are a few features that make it pretty enticing - automatic shut off when it runs out of water and auto adjusts mist level depending on the humidity level in the room. The biggest downside is that it does have a filter you need to replace every few months.
WHITE NOISE MACHINE (optional)
Some parents swear by white noise machines. Others worry about building a sleep dependency. This Healthline article sums up the pros and cons really well. The biggest thing to be aware of when you do use a white noise machine is the decibel level. Most white noise machines can go above the recommended level for infants, so I’d recommend downloading a decibel measuring app on your phone and checking it when you set the level.
If you do choose to use a white noise machine, the go-to is the Hatch. If you’re not sure and don’t want to spend too much, I can recommend some travel sound machines that cost less than $20.
Hatch Baby Rest Sound Machine ($59.99): The Hatch Baby Rest Sound Machine is favored because it can be controlled by an app on your phone, so you don't have to stumble into a dark room to turn it off. It also grows with your little one and offers a time-to-rise feature for older kids (a setting that notifies kids when it's time to get out of bed).
