Less movement at week 16?

I felt baby kicking a ton last week Tuesday (15+2) to Thursday (15+4).

Friday until today (16w) I have felt very few movements. Maybe 1-2 per day, and they have been very light feeling. My mom said baby probably just moved into a position where I can’t feel her as much, but of course I’m freaking out anyway. Someone tell me this is normal 😅
