Tasha,

I started feeling flutters at 13 weeks and full kicks since about week 16. I too only get them when i am sitting still as this is when bubs wakes up. Apparantly when you are active and walking around it rocks your baby to sleep which is why we cant feel it as much (at this stage anyway!!). I'm sure it does kick etc when we are walking around but are probably too preoccupied to notice it! hehe
