Dear Jack
I think a project on sterile vs. clean bottles, and comparison of rate of
"going bad" of both breastmilk and formula would be interesting. Maybe
she could get a lab to check samples every 24-48 hrs. I think I've read
that breastmilk may actually last longer at room temp. than if refrigerated
due to better preservation of WBC's--this would be a good and easy one to
study as well.
All the Best,
