2nd I felt sooner than first but third I felt later then 2nd. All pregnancies are different. I want to say 20 weeks
At 11 weeks with my second, but not until around 18 with my 3rd (22 weeks now and moves daily).
I felt mine at 9wks. I thought I must have been imagining things, but spoke to the dr and he said it very common as 9wks is when they develop their nervous system and jolt a lot. But after that it was a few more weeks before the butterfly feeling developed again.
I didn't feel to much until I was 18-20wks. I'm 30 wks now and it seems like he doesn't stop!!
I actually felt mine about 11.5 weeks but it's not everyday I feel it and I'm 16w6d
