We made sure to check everything they planned on doing - had to sign multiple papers for them not to apply the vaccine and not to put antibiotic cream on their eyes. The only thing they did we didn't like was put that extremely sticky white but-cream on after a diaper change. That stuff is pretty nasty! We used a more natural lighter one that worked incredibly well - never had any issues with nappy-rash and never had a sticky white goo all over them.
