So from what I see here, most of you seem to have or use dopplers. I bought one of the non-doppler things that I am nearly certain is a bit of junk that I will end up tossing. Has anyone had any luck with these? If you did, when did it work? I read a few stories about them not working until you were basically ready to deliver and could see the baby moving all the time anyway, or is it really a matter of patience? I think I am probably a big old chump for buying one of these, but hey, it was only 20 bucks.
