Annie likes to do something i've taken to calling "tummy time", where she will hop up on the desk in front of me and be very nuzzly, and then flop over with her back facing me and demand that I put my hand on her tummy and just gently rub it.
She'll stay like that for a while, like up to 15 minutes and then when she's decided she's done she'll hop up and go wander off again.
