That's great jjsmom!
Baby had me worried today, I've been feeling them every day during the day then just before bed. I'd had nothing all day then had a lie down when I got home from work to feel a few flutters. They picked up when I went to bed though and have been wiggling since. Phew! I know it's too early to kick count but I was starting to panic!
It's funny how you feel them then all of a sudden, no movement. They are moving in there just not as active as they normally are at times. Other times, you are too busy to really notice it. Baby could have been asleep a lot during the day and chose the night time to wake up. A lot of people say they can feel their babies more at night, but again I think it's because they aren't as busy and really pay attention to every little thing they feel.
Try not to panic if you don't feel it for a bit. Next time, drink some orange juice and sit down for a minute and really pay attention.
