Try like a vibrating back massager or loud obnoxious noises. Not your voice or music like annoying sounds. Babies hate it and it makes em move that what my Dr said (:
Baby's are very tired some days and don't move as much as other days.. they have their active days and their rest days.. yesterday my son was kicking me non stop and today he must be sleeping a lot.. but I know he's there.. lol he's had the hiccups and jabbed me a few times. 37+ wks.. but yeah try some ice cold water or some oj.. eat some candy and lay on your left side.. should help..
I found that putting pressure by where my daughter was laying she would move also.
Try drinking something sweet or ice cold. Or even eating candy
