I was rather surprised when I found out I was having twins and instantly thought, there goes my sleep! They were born at 36 weeks but were only a little over 4 pounds so I had some concerns. My twins not only looked different, but everything about them seemed different, down to the way they slept. My one twin would only sleep on her stomach. I was told this was not allowed. The only way she was sleeping was if we would hold her against our chests. The minute we would go to put her down she would cry and scream. We did not know what we were going to do. My friend told me of the Angel monitor. We immediately went out and purchased it. It was great. We were finally able to get some rest without the fear of something happening to our baby. It was also very portable, which was great if we went places or she was staying with a relative. It was also very easy to set up and use. My only complaint was at times it would go off and everything was fine. Overall I would recommend this product, it puts the parents mind at ease and allows everyone to get some much needed rest.
