i was told this and worked for us

i was told more so in new born babies that complete silence can be stressful because they are used to hearing your heart beat and your stomach moving exc. they make toys that make heart beat noise and sounds like they hear inside of you or a ticking clock could help too I did and do this for my baby it seems to help her because i sleep with TV off and lights off and she in our room noticed when it quiet she woke wakes more often

    White noise really helped our baby too.
