The last time we went to play at Penny's cousin's house, all Penny wanted to do was play with her cousin's shopping cart. I was planning to buy one for Penny's birthday, but I decided I couldn't wait a whole month. She's really into taking things out of things, so playing with the cart is ALL SHE WANTS TO DO. I'm like, "Hey, Penny, want to do a puzzle?" And if I try to move her, she throws a fit.
She also tries to walk with the cart, which is highly unstable, so I can't leave her unsupervised. "Hey, Penny, can I go pee?" (Throws fit!) The recommended age is actually 2 years, so I guess it's my own fault if she gets hurt playing "Crazy Shopping Spree."
Hey! Doesn't it sound like she's saying "Yeah!" in the right context? I think that might be Word Number Two.
