When do you

Usually start feeling the baby move when your pregnant with your second? I know you can start feeling them sooner but i can't remember how far a long i was with my first when i felt my son for the first time i just remember he switched side's and my stomach looked like a wave and it freaked me out at first lol

I'm 20 weeks today and feeling a lot of movement, have been getting twitches once in a while for 3-4 weeks.

I want to say I was 14-16 weeks with LO #2.
