My neighbor has 2 little ones and told me to try to lay a heating pad over baby's belly at night to help gas and help calm them down in crib- obviously you put it on LOW and stay there monitoring - take it off after a few minutes. I just tried w my baby that has been fighting sleep for the last couple of days and he fell asleep in minutes in his crib! Winning! (I know someone is going to get mad at me saying this is unsafe- clearly you need to monitor and keep setting low)
