I dont know if were just lucky but our baby has been sleeping through the night since about 8 weeks and only woke for one feed a night prior to that since about 4 weeks

A friend recommended this to me when my baby was 3 weeks old

We didnt have the battery problems one reader mentioned and the 5 minutes was plenty of time to lull the entire family back to sleep

Since then we have used this as the go to shower gift and then finally bought one when we had our own
