I have had several interviews lately where the parents of 1 year olds have chosen to keep their kids on formula versus milk. I made it clear that it is to come pre-mixed and ready to serve, as I do not mix/measure etc. They seemed shocked that I wouldn't do this. When I worked in a centre, it had to be ready to serve, and we were not responsible for mixing it. Is it unreasonable to expect parents to send it already prepared? Thoughts?
