Lately it seems that Ally is understanding the meaning of some certain words. Yesterday morning, she brought me her shoes and said "shoes", so we put on our shoes. Also yesterday, as I was getting her lunch ready I got a slice of cheese out the the fridge and she said "cheese". Today at Meijer, as we walked past the animal section, she pointed at the fish tanks and yelled "fish". I'm very impressed and totally convinced that we're raising a genius. However, she still doesn't quite understand that "no" means "stop what you're doing now"!
