mine was more light taps, but i have never felt previous baby's move early either, people say its like bubbles popping, i never felt my other baby's kick till gone 20 weeks this one was about 17 weeks the earliest ever i have felt movements, midwife told me it was because my tummy muscles are so toned so myabe they slacking now lol. I too was a gymnast and a dancer until after i had my eldest 2 children.
