Almost there!

Ellie is only 3-months old and trying so hard to sit up already. 

Any time she is sitting on any sort of incline, she uses those abs of steel to pull herself up. 

 Then...plop! Down she goes. 

I think she's getting anxious to sit up so she can play with her brother. I would also imagine she is getting bored of her playmat. I mean, there are only so many times a blinking sun and jingling red bird can amuse a person...
