Looks who's sitting up

Aby turns 5 months old tomorrow and the past week she has been sitting up.  She is still very 'humpty dumpty' like but she is enjoying her new vantage point.
She is very much like her brother in that they sit up early in attempts to distract everyone in the fact that they don't want to roll over. She can roll all the way to her side then looks at you like, why would I want to flip all the way on my tummy. I put her on her tummy and she just pushes herself up to see everyone.  Then after about 5 min she yells in frustration and exhaustion.

I was trying to get a picture of everyone together and smiling but

Cleo was a bit distracting for the girls

And when I got their attention, Wil started to smile like a Monster!

So I'm just going to be happy with 2 out of 3
