yeah I was told by the nurse when C got his vacces to be supercareful when washing hands for at least a week to ten days after changing a nappy..it will come out in their pooh. On the nappy front it is advisable to hot wash (60degrees or so) and chuck some canestan or dettol rinse in the nappy wash for this period of time...I always did for acouple of weeks after to be super sure th bugs were gone.....
