I also lie down on my back and balance Siera on my shins.. we call it the "Superman"
She likes music and books so we sing a lot of lullabies and I read her stories. She likes to turn the pages so we only use fabric books or the thick cardboard kinds.
I'm trying to teach her to play with the ring stacker thingy (?) but when I put the rings on, she likes to take them off and throw them. She kind of gets upset when I put the rings back on.
She doesn't much care for any of her toys - they only last 10 minutes or so with her - she'd rather pull up, cruise and explore. So I just follow her around (crawling most of the time, my poor knees!) and point out colors and items.
When it's nice out, I like to take her out as much as I can. We go to the park or we just walk around. She LOVES being outdoors - she stares at everyone and everything. With this cold weather I really don't know what to do with her indoors.
