movement

When am I gonna feel this baby move?! I'm 13 wks and 5 days. I wanna know if I am having a boy or not and I'm super anxious about telling my first born (7yrr princess) she's having a bro or sis !! I almost can't wait til Christmas she has no idea haha but I've been like messing with my stomach to see if I can feel any movement I loved that feeling with my first ugh : impatient I know
