What's wrong with this picture??

Here is a quote from the baby center update I got on my 2 year 3 week old PRESCHOOLER (read: not toddler!) yesterday: "The little sponge following you around has big ears! So give her plenty to listen to. Research shows that preschoolers whose mothers talk often to them build bigger vocabularies. And kids with fathers who also frequently talk to them develop even larger vocabularies. (Moms tend to use more comforting and nurturing words drawn from the child's own world, while dads are more likely to talk about less-familiar interests, researchers say.)" 

 

Do you think a "less familiar interest" could possibly be zergs and terrans and other StarCraft words I should not know? Why does my child look so engrossed? and worse yet, gleeful (if such a word exists)?
