Oh, sound machine. How did I ever live without thee?! This was another pro-tip that I now swear by and is a part of our nightly bedtime routine. We live in a one-bedroom city apartment, and the noise from this Big Red Rooster White Noise Machine drowns out any ambient noise and helps baby sleep soundly. Also, it reminds them of their time in the womb and instantly calms them down. If he's ever fussy in the middle of the night, turning up the sound machine normally does the trick!
