Sure. A talking baby that can predict up to twenty seven years into the future would be badass. The minute I am (re)born I'd say in perfectly clear English "Donald Trump gets elected President in exactly twenty seven years and one week." The look on the Doctor's face would be amazing. 

But even if we cut out the weird shit and assume that this knowledge returns to us at appropriate times in our development, definitely yes. I'd get to relive my childhood, which was pretty great, I'd have no adolescent idiocy, I'd of course be able to make better life decisions, and I'd have all the knowledge I have now as a base to build from, so I'd be a sharp motherfucker.
