Or nursery workers?
Things ended badly with our last nanny. She was with us for about a year doing wraparound care for us. The kids were not happy about it as time went on and were unhappy which then made the nanny feel she had to leave. They were really upset when she went and sometimes it does feel weird still not seeing her. It was a complete break with no goodbyes.
We still however keep in touch with a casual babysitter but not nursery workers.
