Is this a problem?

My 11 month old has now a lot of contact with other family members. He's very social baby.

We were at my uncle's garden and he took him with him to surprise my aunt that lo is there. Later she commented it's frightening that our baby is too friendly. And might be easy for someone to snatch him.

Like what the hell??

At first it was bad that separation anxiety was strong they couldn't hold him and now my baby is too friendly or "trusting" with people (family)???

Well, he doesn't see my father and brother so much as they work hours when baby is more over. But when they are around he cries when he gets picked up.

Help me understand this mess.
