Speaking Better

Lucas has started speaking in 2-3 words sentences now after months on his single syllabus single word!! His pronunciation is very good too. Today he said :
'Green shoes, where?' translated 'Where are my green shoes?'.
'Dad-dy, back home' translated 'Daddy, come home'.
'Mirk, dark, light on' translated 'Meor (the name of the building guard), it's dark, switch on the light'.

He also understand some opposite words as well.
Me: Mummy give you a small candy
Lucas: NO. BIG.

Me: Schh..don't scream. Neighbours are complaining.
Lucas: LOUD.

Me: Careful, the apple is cold.
Lucas: HOT. HOT.
Me: You are bluffing me.
Lucas: Ha..ha..
