So much fun being able to hear them and listen to them moving around! I would highly suggest this for many moms especially to tide you over in between ultrasound appointments to ease anxiety. I feel so much better knowing they are both alive and well in there - instead of my only confirmation being at the doctors apts. I’ve had three US this pregnancy so far and I’m 12 weeks and this is the first time I’ve actually been able to hear the baby’s heartbeat. For some reason they give you the BPM but I’ve never heard it at any of my apts so far. Great purchase.
