I got this app after personally having success with the adult version. First night of my husband being out of town and me getting an 18 month old, 3 year old and 5 year old down I was done! The little one wouldnt go to sleep, he missed daddy and was pretty sick. After two hours of trying on and off he was asleep within 9 minutes! Night two of no daddy, even sicker, followed the apps instructions and played for 15 minutes before bedtime. This time he fell asleep within 10 minutes of trying with just snuggling as he fell asleep. He was babbling and smiling until he fell asleep. Seriously best $1.99 Ive spent since having children. Havent tried with the older two, but they both stretched out and relaxed while it was playing. Magic!
