I don't really have morning sickness (6 weeks pg), but certain smells can send me right over the edge into horrible nausea -- and unfortunately changing my toddler's dirty diapers is one of those smells. Since I'm obviously not going to take the "don't change him" approach (except when DH is around to do it for me), I'm hoping someone has an idea about something that can work to combat a strong reaction to a particular smell. Any ideas? I'd be so grateful!
