After 2 daughters, I thought I had seen everything. My first daughter suffered from a congentital birth defect that required surgery & sleeping on an incline to fix. We used rolled up towels, blankets, even found a bed "wedge." After the birth of our 3rd daughter, we learned she had terrible Acid Reflux. Sleeping on an incline was our only hope at some relief for her, but our old techniques didn't seem so practical this time around. A friend found the Rock N Play Soother online & sent it to us. I was reluctant. My original thought was, "Great, another peice of equipment to clutter my house." I have never been more wrong in my life! She is now 5 months old, and to this day, she sleeps in it. It fits in her crib, in her room & has made a ton of difference! She is a happy baby in the morning, she spits up less. It's so light & convienent that we travel with it also. Our daughter has also always liked to be swaddled. With the design of this Soother, it "holds" her, making her feel secure. I highly recommend this product. It's worth it's weight in gold!
