I have 3 younger brothers, 2 younger sisters, at least 8 elder cousins (7 if you don't count my cousin that just turned 18 last year), and at least 5 younger cousins.
5 siblings and 13 cousins, plus me, total in at 18/19, which is a lot of people, not counting adults and any people I might've forgotten.
So yes. I do have younger siblings and cousins. At least 10 of them.
My reaction would be trying to climb up a pole.
Because at times, I am cowardly.
Same honestly, but not with kids. Just went skating and my cuz had her friends over (she's five). We organized a race together.
