Baby's First Thunderclap

Last night, a storm came through that seemed to produce only one thunderclap, lots of rain, but only one, very loud thunderclap. It happened around 1:00 am and woke me, Hayden, the cat and the unborn baby up. Shortly after the thunder clapped, Hayden felt a stirring in her belly and a few kicks. I wonder if it scared the baby. I would like to think that fear does not exist in the womb. I'm thinking it just woke the baby up and he/she was blissfully unaware of anything other than a loud noise - a muffled loud noise. When and why did we become afraid of thunder when we were kids? Or afraid of anything? I think it would have to be that time after you've gained knowledge of a thing but before you've gained enough knowledge of the thing to render it harmless, the wisdom to avoid it, the courage to confront it, or the love to.... conquer it? I dunno. I'm mad at that cloud for waking my baby up. And now, I gotta get back to work.
