I don't the the gender of our little one either but the last time we got a read on the heartbeat it was 150. I don't know if that's high or low... I think it's a boy though so we'll see what comes in July!
The little bugger likes to do most of his kicking at 3 or 4 in the morning. Not the gentle little nudges I get throughout the day, but the hard core wham bam here I am knocks that you can feel really well from the outside. I think he likes to remind me he's still there. I love it, but the lack of sleep is wearing on me. He only seems to move if I've been still for a while. Maybe I should starting sleeping in a hammock? Actually that sounds kind of nice, although I'm picturing the hammock on the beach in some tropical locale!
