If you can feel you're baby move 10 times in a day then thats good. If she still worries, she needs to lie down for a long time and totally relax and focus on nothing other than when the baby is moving. If she has concerns, she should phone the labour ward, they will probably call her in to have a trace, so she presses a button every time she feels the baby move and this should correlate on a graph of the baby's heartbeat. I had pre~eclapmsia with my first, and I thought I couldnt feel anything, yet when I went in and had nothing to focus on other than the baby moving, little blighter was actually going about 10 times every half an hour.
