i think a doppler would make me too nervous as well, when i was in labour with ds3 they couldnt find his hearbeat at one point, and it was AWFUL really traumatic and stressful, i would worry too much if i had my own doppler.
i have to say that this little one is REALLY wriggly, particularly in the evening, so i know he is just fine, which has been reassuring the past few days as i have been really ill. when i lie down you can see my belly move and ds1 and dp have both felt him kicking
i am chuffed as i just got a maternity pillow of ebay, its one of the HUGE grobag ones that are normally £40, i got it for a tenner now i cant wait for it to arrive, i dont have a bump yet but it will be great for my pelvis
