Had a situation the other day at my sister's where she told her 3 yo to take my 2.1yo ds upstairs to play in his room. I felt a bit uneasy about this as when they are together they do go completely hyper, and my ds doesn't really understand the danger of doing certain things ie sticking something into a plug socket.
Am I being "precious" or a "helicopter parent"?
FWIW I would be quite happy to leave him if he was a bit older/more understanding of things that are potentially harmful.
