?? I know this may sound daft

But looking for some advice LO has no awareness of strangers - will talk to anyone and everyone - wants cuddles and kisses from pretty much everyone - will go off with anyone and just generally too trusting.

Child is very nearly 3yrs old - and sits approx between 16-26 and 22-36 mnth category in each LD area

Without scaring the LO to death any tips how to encourage some questioning/concern

Child follows other safety boundaries such as holding hand near road etc althought not 100% sure if this is just routine or understanding of danger.

TIA xT
