Bests & Worsts Reviews from Amazon

My baby had a hard time pooping while he was sleeping and would SCREAM and SCREAM. I got this and stuck it in, and after it being in for like 20 seconds it start to whistle, then vibrate, then the explosion began. My baby would literally sigh in relief. It was crazy screaming in pain one second than a split second later a sigh and a peaceful face. I did reuse these. I washed them with soap right after use, and stored them in a cup. When the cup was full I filled it with water and pop it in the microwave for a few mins.
