Lots of movement! Normal???

I'm feeling so much movement the last few days!! I'm five and 1/2 months along. I feel baby kicking up towards my ribs, my sides, and some are big! Today she's been active since I woke up, and pretty much all day. Is that normal? And with her being the size of a "large zuchinni" is it possible to feel movements up near my rib cage at this point? The kicks feel so high up!
