This is an okay thing for her developmentally, and I'd only be concerned if it goes on for more than a few weeks. If she starts to cry and reach for you pick her up, give her a cuddle, all the while calmly and cheerfully saying, "Little Susie came over to see you, she wants to play with you. Do you want to show her your red ball?" and re-engage her with a favorite toy. If that doesn't work just let her engage with people from the safety of your arms (unless, of course, you're tending to the other child or something else prevents you from doing so). Don't refuse to reassure her just on principle though, and don't make the reassurance sound like something COULD have been wrong - she really just wants to know she can depend on you to be there when it gets to be too much for her.
What makes you think this is developmently normal behavior?
