Inner city park with gated playground. It has a mound for a big slide and there's a grassy bit behind for running about so can't spot DC easily if they go that way unless you're on top of the mound (being eaten by flies
).
I like to allow my DCs space away from me to develop resilience and social skills so I take my blanket and sit in the main bit of the playground where I can see the gate.
Eldest is 8, youngest 4.
Is this ok or should I be following (particularly youngest) around still?
