How long should you use white noise for a baby?

You can use white noise for as long as it seems helpful, but most experts suggest limiting it to sleep periods rather than playing it all day. In the early months, it is common to run it for the duration of naps and overnight sleep, as babies wake frequently and are easily disturbed by noise. As your baby gets older and sleep becomes more predictable, you may choose to use our machines’ timer so it turns off after, say, 30–90 minutes, or gradually lower the volume once your baby is settled. There is no strict age at which you must stop as long as it’s helping you and your baby sleep better.
