18 weeks baby kicks

I’m 18 weeks now and for the past week I’ve been feeling little movements and little twitches. It’s now turned into stronger and more noticeable kicks. My mom insists that it’s too early and it’s probably just gas because she didn’t feel the baby kicking until 20-22 weeks but every pregnancy is different and I know that it’s not movement or something to do with my body. I know it’s my baby. I guess I have a strong boy. Are any of you ladies early kickers too?
