A is pretty shy when we get around people she doesn't know or large groups of people, like a family gathering/party/holiday event. It takes her quite some time to warm up and when that finally happens it's usually time to go. E is in her separation anxiety phase so she cries when people get up in her face (I would too) but is ok and will smile if I'm holding her.
Is your LO shy around people they don't know well, or if they are in large group? Or are they pretty outgoing?
