We had our daughter in December, and with the boys (now ages 4 and 3) it is impossible to keep the house quiet for nap time. She wakes up at the drop of a pin as well. I swear, one night she woke from the sound of me tearing the toilet paper off the roll. I decided to take a whack at a sound machine for her room, to drown out the noise from the rest of the house. She always slept really good when she was in our room with us, and we have a fan going all night. I figured it couldn't hurt.
I read a few reviews online and found this little guy at Target.. The SoundSpa Slumber Whale from mybaby by Homedics! From reading the box I could tell that the Slumber Whale had some awesome features, and was only $29.99, so he (she?) came home with me.
So. The white noise sound setting on the Slumber Whale is exactly what I was looking for- a steady and constant noise that sounds like a fan. I didn't care about the nature or ocean sounds, but they're included as well. There are three lullabies, an ocean wave sound and a heartbeat sound to choose from. There is a volume control knob to make it as loud or as quiet as I want. A little feature that seriously went above and beyond my expectations- when you turn the sound on, it starts out quiet and gradually gets louder until it reaches the volume that you have it set on. I especially love that it doesn't come on full volume when I'm taking Olive to her room for a nap and I have to turn it on. There's no sudden noise to wake her up. I love that the speaker is nice and big and the sound throws nicely to fill the whole room.
If you are looking to buy a sound machine for your little one, I highly, HIGHLY recommend the Soundspa Slumber Whale! I really don't think you'll regret it :)
UPDATE: JULY 26th, 2013
One of the lights on the projector has burned out :( For a few days, the faulty light was creating a strobe-light effect in Olive's room as it was obviously in the process of burning out. It quit working completely and now we can't use the projector as a night light. I checked my receipt, and we bought the Slumber Whale on April 13th. We started using the projector as a night light approximately two weeks after we bought it. This means that the lightbulb lasted about three months. I'm not happy. I had actually read a few reviews online (before I bought it) by people who had the lights on theirs burn out, but I thought that the good reviews outweighed the bad. We had grown to love the projector feature so much and now that we can't use it, I am very disappointed. I wish I could take it back to Target to exchange for a new one.
