Turning on the white noise machine has always been part of our nap and bedtime routine. Eli is 10 weeks old and he has always been sleeping with the white noise on the whole time. volume is loud enough so we don't have to be sneaking around the house worrying that we will wake him... Does your LO sleep with white noise in the background? Should I be worried that he won't be able to sleep w/o some noise in the background? Did you have to wean your LO off of it?
