Doctors have told me that it is very well,possible to feel your baby move sooner with a second or third pregnancy. I felt my second son when i was 9 weeks.
I have felt the flutters, but it is mostly attributed to gas bubbles in my tummy. However i had an ultra sound last week and my baby was wiggling and moving its arms. I am just now 11 weeks.
At 8 weeks you Uterus is almost doubling in size, this causes the flutters or even tickling. I've been feeling tickling under the skin for the last 2 weeks :P
Your baby most certainly is moving around a lot. Usually people don't feel it but everyone is different, it's possible.
I feel something but I feel it might be the uterus, (which is the size of a grapefruit at 8-9 weeks) being pushed around by the gas. Our bodies do crazy things while pregnant ;-)
Definitely not the baby moving at 8 weeks.
the baby isn't actually capable of moving until closer to 12 weeks. before that all they can really do is vibrate. you can't feel anything I promise.
