White noise has been a staple in my household since, forever.
I added a white noise machine to every child's bedroom and to my own.
I recommend a white noise machine for yourself when you bring puppy home and you are crate training. ONLY if you are comfortable with it though. Many parents just put the puppy in the same room with them and the white noise helps everyone and you can still hear the puppy since they are right next to you.
Anyway, here are some videos I have put together that will hopefully be helpful to you.
Congrats on your new baby and welcome to the HOB family!
