Isaac's favourite word is 'Daddy', which he repeats all day.  He often brings books for Daddy to read and plops himself (in particular his bum) violently, heavily onto Daddy's lap, uninvited.  Lately he pulls Daddy by the finger toward some destination, in order to show or to communicate something.  Yesterday he pulled Daddy toward a chair and said 'sit'.  When Daddy asks, 'Who wants [insert good thing here]?', Isaac answers, 'Me'.  (This is similar to 'Look both ways... Go!', in that it is a response to a cue or prompt.)  Daddy's question is really intended for Dylan, but Isaac answers.

Isaac has developed a bad habit of biting his Mummy or Daddy (lately it is Daddy) when he wants attention or feels he is being ignored.  Last week Daddy made the mistake of checking his mobile phone while standing near the doorway, and Isaac bit Daddy on the bum cheek, rather hard.  Daddy did not even hear Isaac approaching from behind.

While finger-painting today, Daddy asked Dylan if an apron would be necessary.  'You mean an aprint', Dylan corrected Daddy.  Daddy at first insisted the word was indeed 'apron', but Dylan disagreed.  For the rest of the day, Daddy chose to call it an 'aprint' too, like Dylan, to save argument.

Isaac says 'bubble'.

Dylan is constantly asking questions the answer to which is 'Objects at rest remain at rest; objects in motion etc.', but we haven't been able to communicate the answer, yet.

Isaac spotted a blackbird, which he followed around the playground for several minutes.  At first he followed at five feet, causing the bird occasionally to hop or fly a small distance away.  Isaac then widened the gap to ten feet, at which distance the bird was unaffected.  The boy stalked the bird, not to harm it, but only to observe it.  He watched as the bird pecked at the grass and hopped in and out of the playground fence.  When at last the bird flew fifty yards beyond the playground, Isaac opened the gate and wandered around looking for it, until he gave up.  He later observed two squirrels and a wood pigeon (not the common street sort) for several minutes each.  The wood pigeon allowed Isaac to come within three feet.  Isaac never attempted to disturb the animals.  He just watched them.  He seems very interested in their behaviour.

DYLAN TO DADDY:  How old are you?  Are you older than twelve?  Wow.

DYLAN:  Where on the airplane does the pilot pee?  Maybe his pilot's chair is a toilet.

Daddy usually says to Dylan at intersections, 'Look both ways... Go!'

Today when Daddy said 'Look both ways...', Isaac shouted 'Go!'

'What are trees made of?' asked Dylan. 

'Cellulose', said Daddy. 

'How are trees built?' asked Dylan.

Dylan assumes that everything in the universe is a human artifice.  Everything, in his view, is built.

'Trees planted themselves and grew before humans existed', said Daddy. 

'How was the first human born?' asked Dylan.

Isaac says 'poo' in connection with his poo.

He also says 'come in' when you knock on his door.
