The grandparent of the child I nanny says things that make me think this all the time.
My nanny family doesn’t use any physical punishment at all. Well she said if we don’t start spanking the kids a (3 and 1 year old) they’ll become unruly demons.
Despite the no spanking policy she still spanks the 3 year old. We stop letting her babysit after that. She still wants to babysit and after a lot of begging we finally let her have the 3 year old for the weekend.
Well the 3 year old came back and was obviously spanked. Also despite her being potty trained she came back in a diaper too. Somehow she managed to undo days of potty training in a weekend. Now the 3 year old is back in diapers full time because she refuses to use the potty now.
Most older generations are so out of touch with reality when it comes to childcare.
