Ours has 4 different soothing sounds. Stream, rain, ocean and whales. There are 2 different time settings, 23 and 45 minutes. We usually have it set on ocean for 45 minutes.
Everybody kept on suggesting white noise and guess what? They were right!
So, thank you granma Hayes (we are not sure yet about this name. ;)) for getting us not just the Sleep sheep but most importantly….SLEEP!
