Ask Robbie about his teething experience (direct quote, "Waaaaaaah!"). Then go home and give Sonya a hug for saving you from having to reincarnate and go through that at least a dozen times more than you will have to now.
Not to mention birth trauma, learning to walk and talk (and sing and play instruments) from scratch, having diapers changed in cold rooms/tents or other uncomfortable environments, etc. Aren't you lucky to have Sonya? :^)
