My niece is two-and-a-half. After a whole lot of developmental therapy, she's finally caught up with her language skills. I was a bright and extremely articulate two-year-old, and it wasn't until now that I realized most kids that age are still sticking two or three words together and not having full-blown conversations. Also, they are largely unintelligible to people who don't talk to them every day.
I've concluded that two-year-olds are pretty boring, and I'm dying for my niece to get to the stage where she starts asking 'why?' so I can explain the world to her. Watching a kid develop is pretty damned slow, it seems like her milestones just get further and further apart. I absolutely cannot wait until she turns into a real person, it feels like I've been waiting for eternity. Maybe she'll turn out to be really fun in another year or so. Right now she's just kind of fun.
