Lily is in full on chatterbox sentence mode, albeit fairly short sentences...what they lack in structure however, they make up in frequency. I wouldn't be able to attempt to hazard a guess at how large her vocabulary is now, but often she will comes out with words I didn't even know she knew. Some still remain her own special invention and no matter how often you tell her it's a horse she will still insist on referring to them as Gee-Gaws (or flop-flops for flip flops but because this makes me laugh so, I am not hot on correcting her.)
She is also pretty spectacular on question posing, sometimes utilising the phrase "What that be?", which makes her sound like she originates from the West Country. On reflection it is quite impressive how few "what that be?"s can wear a person down.
