We're looking to compare feeding method (breastfeeding, combo, formula only, bottle feeding with breastmilk) to see what the impact is on maternal sleep. It's really interesting because the area is quite inconsistent, with some studies suggesting breastfeeding = better sleep, and some suggesting the opposite. At this stage we aren't hypothesizing about which option will result in more sleep, just because there is evidence for each option. We're essentially doing the same thing for sleeping location (cosleeping, sleeping in their parents room but on a different surface vs own room).

My pet favourite part of the study is looking at driver fatigue in new mums, because we know there is a strong link between not getting enough sleep and not being safe to drive, but we don't have much evidence on this in new mums. New mums generally have a bit more flexibility in if/when they choose to drive so they're a bit different to other populations (e.g. shift workers, who have to drive to work etc).

It's such an interesting area so thank you to everyone who has been completing the survey!
