oh yes,with DD(who is now 2 and well and truly making up for it!!)i had to be monitored all the time from about 26 weeks,they felt she wasnt moving enough,so much so they borught me on early and even opted for emergency ceaser all because they felt she wasnt moving enough yet she was fine,perfect,i think some babies move more than others,i swear i hardly ever felt her unless she had hiccups and had to go up the hospital every week for monitoring yet this time im 25 weeks and pregnant with a boy and he just goes like mad my whole belly moves like crazy totally different to my DD i am in shock becuase its so different!It is worrying though you cant help it,but i really think there just all different!
