Pregnancy Forum - Too Much Movement?

I have a question about fetal movement. I've tried to do some research on this myself, and it looks like I don't have anything to worry about, but I wanted to get others' opinions.

I'm 33 weeks pregnant with my second child. What they say about every pregnancy being different is so true. I can hardly believe this child has the same genes as my oldest. Anyway, my question is about fetal movement. I know that we are supposed to do kick counts every so often, and that the target number of movements is 10 within 2 hours. With my first child, it was never a problem hitting that target movement. He would have periods of movement, then rest, then movement, then rest. Sometimes he would kick hard enough to make my belly jiggle, and by the end of my pregnancy we could see the outlines of little feet and elbows when he really got active.

This time around, I started feeling movement *really* early, like around 13 weeks. This baby is much, much, much more active than my first one. It seems like it never stops, just slows down to a gentle rumble for a half-hour or so, then charges back up to full-blown mania for hours and hours at a time. It stretches and kicks and rolls so hard and so frequently that I feel bruised on the inside all the time. When I do kick counts, which I try to time during the "down" periods, it averages 100 or more movements every 20 minutes. I told my doctor this and he said, "it sounds like hiccups to me." these are not hiccups! The movements are strong enough to shape and mold my belly, and occasionally even shake the bed when my husband and I are both lying on it.

My midwife says that a lot of fetal activity is a good thing, because it means the baby is well-nourished and healthy enough to use its energy for movement, instead of just lying still and growing. So, even when i'm almost crying from being so sore, I can't wish that it will stop. My husband, though, is worried that the baby might be having seizures or something in utero. I haven't found anything in my research that concerns me about this. Just that if the movement becomes "unusually" intense and is followed by no movement at all, that could be a sign of trauma or distress. Since this activity has been going on for months and months, I can't call it "unusual," and it's certainly never followed by no activity at all.

Has anyone ever heard of a baby being too active in the womb and what it might be a sign of? Should I just count my blessings that I have such a healthy, active baby?
