My OTR microwave instructions were 30 min clearance between the bottom of the cabinet and the top of the cooktop. I have 32 total, so my microwave is about 16 over the gas cooktop. It passed the code inspections at that height.
There are some ways to get baby's attention, but if fetal movement isn't felt enough, call the doctor. The gentle rocking of mom's everyday movement most often lulls the baby to sleep, hence baby sleeps all day and wakes up when things get calm at night. To alert baby, simply lie down for an hour or two and chances are she'll wake up and move around. While you are reclining, change your position occasionally, between lying on your back to lying on your side, for example.
If you have felt your baby move, but the movements have not been regular, remember that you may not feel the movements consistently until your baby is larger. As your pregnancy progresses and you reach your third trimester, you should feel your baby move regularly. That's when you should begin to pay closer attention to your baby's movements, because as your pregnancy continues, a sudden change in the amount of fetal movement may be a red flag that there is a problem.
