How's this for a shocker? A 2010 study found that new moms actually log plenty of shuteye hours; they just don't get good quality sleep.
One of the biggest hindrances keeping you from sleeping well is not only worrying that your baby's going to wake up in the middle of the night, but also wondering what he wants when he does.
If you think he might be wet, needs to eat or is otherwise uncomfortable, it's important to check on him. But it doesn't always have to be mommy to the rescue -- enlist daddy to help, or have the grandparents sleep over occasionally so you don't have to wake up every single time.
