This may offend some (and this is purely my own opinion), but I would be going into the centre and smelling the carers.....I hated working in Aged Care with heavy smokers as they'd come back from breaks and just stink....poor residents. Plus if they don't wash their hands there would still be nicotine on their fingers and I don't want my baby to have any contact with it....
Aaah, sorry to all the smokers out there.
