If your son has dark red hair, is between 3-5 years old and plays in Garfield park with his 30 something year old Latina nanny...you should consider getting a new nanny.
She doesn't watch your child. He is climbing on very high structures with only socks on. A fall -which seemed imminent- would be a certain broken bone. She is certainly not teaching him or helping him. He isn't learning how to interact appropriately with other children because he is completely ignored. When I tried to find who was with this child she did not identify herself, as she was paying so little attention she didn't even hear me questioning everyone. She had a hat pulled down and was on the phone for over 1/2 hour ignoring him. He could have been hurt, taken or anything. She absolutely does not care about your child. This is clear.
When I finally identified her because he ran to her (he had been playing alone unattended for an hour), she was dismissive and rude. I pointed out she was hired to care for a child and she just kept talking on the phone. She is, bar none, the worst nanny I have encountered. Something bad eventually will happen, and you will have no way of knowing if it was preventable, because she will say, "He was just playing...he's such an active boy... and I was standing RIGHT there and he fell. There was nothing I could do--it happened so fast." I guarantee you will have this conversation. And I hope it is that conversation and not that he has been snatched by a stranger, because I could have taken him screaming from the park and she wouldn't have looked up. She was far away and completely immersed in her call. If she did it that day, she does it every day.
To the OP: the City and State wasn't specified so I looked up Garfield Park. If I am incorrect, please let me know. Thank you!
