Everyone thinks their kid is a prodigy of something.. Whether they can hit a golf ball at 2 (my son is the next Tiger Woods) or they can write their name at 3 (they're going to become the next great author), and so on and so forth.
Truth is, prodigal-type talent is mostly inherited. I have no concrete data to back that up, but just indulge me here. My guess is the reason Jason Bonham is such a kick ass drummer is because his father was such a kick ass drummer. And when you are around that type of environment when you are growing up, the part of you that inherited it comes out if fostered correctly. That doesn't mean that kids who don't have John Bonham as their father won't grow up to be amazing drummers, it just helps a little bit..
But don't worry if your child isn't exhibiting signs of being a prodigy of athletics, mathematics, science or anything for that matter. Sometimes a kid is just a kid. The majority of them are. I took the Twinado bowling by myself this Sat morning and then we spent a few hours outside at the playground, the soccer field and the track. Man, were they pooped! (and so was I). They got great exercise on a gorgeous early spring day and now they are relaxing because they are tired. Sometimes I think we push our kids too hard because it's important to have them try so many different things to figure out what they like and what the don't.
Sometimes we just need to let them be kids and I think they'll figure that out all in good time.
Oh, by the way, this is prodigy drummer I recently saw on the interwebs.. He's 6.
