Aims with her bum

Recently, she's been doing something rather amusing, to me at least. Papa hasn't had the chance to witness it yet.
 
First time was with the Potette Plus, minus the plastic bag. Since it is 'clean', I allowed her to do what she wished with it.
 
She pulled it near the bed. Pulled herself up beside the bed. Used her leg to kick it around a bit while holding the bed for support. Then she tries to sit on it, at first I thought, like a stool, off centre or too far back. When she finally sits right in the middle, as a potty, she flaps her arms happily and pants in bliss, then only did I realize what she was trying to do! Praises, lots of cooing, clapping and kissing! And she attempts again, a few more times :)
 
Today, she does it again. This time, with the new rubber duck that Papa just bought. She throws it forward, back, then she crawls in front of it, and starts pushing her butt up in the air, as if reverse parking, then attempts to land on the duck. When she finally hits spot on and the duck squeaked loudly in protest, she again flaps her arms and pants happily! Then only Mummy realized, she was trying to make duck squeak by sitting on it. She does this one more time when we're in bed, throws duck off bed, the muddle around the edge, and squeak! Happy baby. Mummy was floored with laughter.
 
Sigh. The things Ning do. Should video! Where's that camera?!
