I bought her heating pads before the birth of my baby. during the first week of life of my daughter I have not used them I told myself that it was an unnecessary purchase until the moment my daughter had colic. so I've used to put on her belly (slightly warmed) .Then there was 3/4 weeks to his growth spurt and so she asked enormously breast. so I used the pads for me and the heat has faded pain ..! Another use ... when my baby falls asleep in my arms and I puts it back into its cradle, I heat before the two pads and I "heats" his bed, and the transfer "arm hot / cold bed" is less difficult and it avoids it wakes up! So in the end I'm very glad I bought it!
