I purchased this bear when my baby was 7 weeks old as she could not settle to sleep easily. We use the sound unit strapped to the cot on its own as the bear is a bit cumbersome. We did not see a magic cure of instant calming as soon as the monitor went on,as I had hoped, but she did start to settle better within the first two weeks of using it. Now at 3 months old she starts to wake, the unit activates and she is comforted and can sleep for 30 mins longer, so it works wonders for us, I also find the sound soothing and it helps me sleep after a night time feed. I would definitely recommend this bear and will be purchasing as gifts for pregnant friends.
