Bunny kicking while nursing?

Bunny&Bear+2 • Married the Love of my Life: 9/2013 DD1: 1/2014. DD2: 6/2019 (Miscarriages: 10/2015, 1/2016, 4/2016, 6/2016, 5/2017)

Occasionally my baby will be nursing while laying on the boppy, and her top leg (usually) will start vibrating in a way that can only be described as like a bunny kick... anyone else have a little one who does this too? Or know what it means? (If anything?)
