Second time moms! When did you feel baby #2 start moving?

I’m 18 weeks pregnant with my second baby. With my son, everything was smooth sailing and I just loved being pregnant. Everything about this pregnancy is totally different. Honestly I can’t remember when I started feeling my son move, but I swear it was earlier than this... plus by OB keeps asking if I feel the baby moving. So far, I don’t think so. I remember with my son it was super clear and I knew right away he was moving. I have my gender/20 week ultrasound next Friday, and would love if I started feeling something...

Any other moms have a second pregnancy that was drastically different than the first?
