We had 2 childminders and the issue you mention:
-Our son was taken in the pushchair every day to pick up the CM’s own kids from school
-We had to take lots of time off work for the CM to take her kids to medical appointments
The other issues we had were:
-One quitting suddenly and leaving us in the shit
-One having tv on all day, not encouraging development eg spoon feeding instead of letting him use cutlery
-Sending my son home all the time for nothing, eg even when GPs said he was fine. Trying to diagnose autism without any medical training
-Constantly sending wrong invoices. Forgetting to give us all dates of their annual leave
-Incident where my son was badly scratched by their pet
I live on a street with a childminding couple and personally know 3 people who have removed their kids from their care due to bad issues.
We moved our son to nursery and it’s been amazing, and will send our DC2 there from 11 months. Don’t worry about sending your kid to nursery :)
