Sierra's speech has exploded lately and she is talking in very long sentences, I wish I could understand them though. I do understand this one "At's petty poo". She is saying "That's pretty cool". So now when I think something is pretty cool I have been saying "at's petty poo", which could be misunderstood for something petty and stinky I guess. Better watch who I say it to! Here is a picture of her I took when she put her swim goggles on, which she thought was petty poo!
