I feel my baby pushing her head down

I'm about 31 weeks and feel this pretty much daily now. Does anyone else feel this? It's not painful, unless she's pushing into my cervix, but it feels weird. I don't remember that feeling with my first. I know she's been head down for quite some time, I know she's low but hasn't "dropped", but I can feel her little head pushing down down down every so often. I especially notice it when I'm sitting. Lol
