I first felt my baby moving inside of me early as 11 weeks, but i didn't feel her actually 'kick' until about 16 weeks. Ever since then, she has been kicking constantly all over the place, and hard. So, no, you can't tell the sex by the kicking because babies will always change positions until mid to late in the third trimester when their head will go down in the pelvis to get ready for birth. At that time, you'll most likely get a few shots in the ribs.
