Quoting Megsyrk26:" maybe its just me but my son is very active normally and for some reason today i have not felt him move ... [snip!] ... have tried drinking a cold glass of water. talking to him even ate ice cream but no response and its starting to make me worry."
I went more than 8 hours before without feeling movement a few times, especially the closer I got to my labor. I don't know how far along you are, but if you are super concerned about it, or do not feel the baby within a few more hours, I would call your obgyn and go get monitored.
