I pick teen over babies, but what I really want to see vamped up are elders. They have nothing. They're just adulting who are too tired to do anything and can die from woo hoo. Where's the posting pictures of grandkids on Facebook? Knitting? Assisted living homes? Scrapbooking? Shuffleboard? Randomly longing to visit their adult kids/grandkids? Asking their grandkids to go on special outings with them? Grandparents day? I want fun things for elders because you should be able to have fun with every lifestyle.
Baby isn't really a real life stage and it doesn't last long, so I'm okay with it the way it is. Teen definitely needs work, but they recently got some help with parenthood and elder is definitely much more neglected.
