Julia O'Brien isn't sleeping much these days, she's nursing her one month old son Liam around the clock.
"I usually try to go to bed around 10 and then he usually needs to be fed around 11:30 or 12 and then he eats again around 2 or 3 and then again around 5 or 6." said Julia O'Brian, a new mother.
Because of that demanding schedule, many new moms choose formula instead.
With bottle feeding, dad can help out overnight, plus some people believe formula fed babies sleep better.
But a new study from the American Academy of Pediatrics says mom won't get more sleep using formula.
Researchers had 80 news moms wear sleep monitors. They found all new mothers got the same amount of sleep and were equally exhausted
"The point that we can now tell mothers is if you want to give up on breastfeeding because you think your baby is going to sleep longer or you'll be less tired, that's not true." said Chairman of Pediatrics at the Long Island College Hospital, Dr. Stephen Turner.
Doctors hope the results will encourage more women to breast feed - which has been shown to be much healthier for the mom and baby.
Dr. Turner says breast fed babies have a lower risk of obesity and allergies. They also do better on IQ tests, and are generally healthier.
"Breast fed babies are less sick, they're getting antibodies in the breast milk, it helps protect them from illness." said Dr. Turner.
For Julia, the study reinforced her choice;
"It's wonderful to be able to bond with him and I think it's made the transition into motherhood a lot easier." said Julia.
There's an added benefit for breastfeeding moms, they tend to lose their baby weight faster.
The American Academy of Pediatrics recommends babies be exclusively breast-fed for six months and continue to receive breast milk for at least a year
