This thing has been worth its weight in gold. My LO is very active...always has been. One night I needed something to soothe her...I was desperate and tired. I got this thing and put it next to my tummy for her to listen to. This started at about 28-29 weeks and now at 37 it's my fave item!!! She calms down as soon as she hears it 💗 I'm thinking she may love it when she gets here too :) definitely recommend this even while they are in the womb.
