Oh yeah, i started feeling movement with my second baby MUCH MUCH sooner than with my first dd. Now at 24wks I feel movement everyday for most of the day and have been since probably 21wks. I think i felt my first movement very early, say 14wks or so.
They say with each pregnancy you have, it will be easier to feel and recognize movements early on. You are most likely feeling the baby since you know what to look for this time around! =)
