It seems like it's more common and also maybe more acceptable (??) to call adult daughters names like sweetie, etc. MIL keeps calling DH sweetie and honey (he's almost 40) and it makes us both uncomfortable. She's always called him by his childhood nickname (for example Johnny for John) which is annoying but tolerable. My name for him has always been hon, so just since we've been married she started calling him honey all.the.time. For example last night I said something funny to him and he laughed and she leaned across the table and said "what are you laughing at honey?". Just weird, but then again, it's just one of the many things that bug me about her, and yes, it's very minor so I was just curious about other families. My parents call me and my siblings only by our names and I call my 2 older daughters by their names unless they're sick or upset about something, then I might say "O I'm sorry you don't feel good sweetie".
