Wooshh is suitable from birth upwards but should always be positioned well out of reach of the baby / child.
It is great for children and adults too. We deliberately designed the range of sounds to include those that were also pleasant to adults – the purring cat, ambient music, water and rain sounds in particular. There’s nothing worse than hearing the same badly looped nursery rhyme all night!
We also invested extra to improve the sound chip to near CD quality, so that there were no harsh digital distortions in the sounds which are so common in cheaper sound machines.
