when did you feel the movement of your twins?

Pamela • Son Patrick 3/6/06. Chemical pregnancy 11/2016. Baby girl/boy twins Liliana and Alexander 11/7/17
This is my second and third child. When baby B was on my lower left side I could feel the flutters at 12 weeks. Now he moved above his sister who on the lower right side. I haven't felt either of them. I'm 18+1. They are doing well and moving during every sonogram and both their heart beats are easily detected on the Doppler. When did everyone feel their little ones?
