good thought there Leesha.

I often wander what Lachlan thinks about his hands, he stares at them for ages.
He isnt waving yet but has the motion going just not at the right time.

He understand what no means, DH said to him the other day "you know what that means dont you Lachlan" cause if you say No to him he has a paddy.
He also knows if he turns the tv off while the kids are watching it he will get a reaction.

I am sure Lachlan has boobie dreams too, he smiles and goos in his sleep.
He knows who Mummy and Daddy are, during the day i hear Dad da da all day , when dad comes home he gets a big smile and a dada. I only get Mumma when he is hungry and really tired, im sure its just cause he knows Mum has the boobs and thats what he wants when he is tired and hungry.
I am sure they understand more then we think, i love watching him sit and watch what his older siblings are doing he just takes it all in.
