I just did a settling in morning at DS nursery. It's not great but it's are only option currently as in the middle of moving. There were 9 children under 2 so 3 staff members. I was there around an hour and on multiple occasions one or two members of staff left the room for around 5 mins. Is that legal? There were times where it was only me and only one other worker for 8 children while one went to change a baby. The other just disappeared. Should I raise with the nursery manager or is 5 minutes without the correct ratio okay? I dread to imagine what it's like when they are not being observed.
