My daughter received the ‘mouse warmer’ and we tried it out this weekend. He actually slept in his crib a few hours! (We used it as a warmer and on his stomach while all swaddled up). Two of the nights I was there, he slept on me all swaddled with the mouse. He slept from 12 to 7:30 AM. My daughter thanked me for some badly needed uninterrupted sleep. Now we try the crib at night with the mouse. Thanks again – something worked!
