Okay, here's an odd problem. My baby is pretty vocal, but when we are out in public, at a grocery store or a restaurant, he yells! He's not crying or in a bad mood, he just seems like he wants to be heard. I talk to him to let him know I'm listening to him or try to shush him a little if we're in a restaurant but I don't really know what the right move is here. He's happy when he does it so I don't think he needs soothing and I think it's still kind of early to teach him polite behavior in public, right? Any suggestions how to keep him from annoying other people without losing his love of "chatting"?
