I think it also depends on the baby as with my first i had a very active boy who wriggled and kicked constantly and I first felt movement around 16 weeks. With my second baby I had a fairly gentle girl and her movements were more like slow stretches and i didn't feel her move much untill she was big enough to overtake my belly LOL. This one I've been feeling movement for a few weeks but it's not an every day thing however it's getting stronger and more often as the weeks go on.
