My mom wants me to buy something like this she saw in a mall somewhere in Manila. Will this help in my toddler's sleep at night?

based on experience, my toddler prefers music and soothing sounds more than lights. For some reason, projected lights make him uneasy. I'm not sure, though, if it's because the patterns projected are strange from his POV. I'm planning to changing his night light just to be sure.

We have something that resembles this, although ours is lullaby projector. While the music has been effective in making my bub sleepy, the projected lights made him all the more awaken and attentive. I wouldn't void it being useful at all. It helps to try. :)
