Hi S.,
We have a fisher price soothe and glow seahorse. He's blue and his tummy lights up with a yellow glow when pressed and lullabies play for about 3-4 minutes. It's easy enough to press that our son (13 months) can turn it on himself. We can usually tell when he's rolling around at night in the crib because he will lay on it and it will go off. :) There are two volume settings though so you can turn it down if you want. HTH!
