Well, I got the conair machine from Target, available online only, cost about $28 total, which was more than I wanted to spend, but got it anyway.
I personally really like it, esp the water sounds. I have noticed it takes Riley longer to go to sleep with it on though
And then this is what happened last night about 3 am ish. We cosleep, so I felt him touching me and saying, "Moma, Moma?" I woke up, and he was sitting up on the bed, pointing to the machine, saying, "Wa-wa's wet! Wa-wa's wet!" (Water is wet).
Cute but not what I want to hear at that time of the morning!
I am going to give it a few more days to see if it will have any benefit, and I really find it soothing for me, but not so much for Riley so far. I will try different sounds, but some of them are a bit annoying to me, like the birds chirping etc.
