DYLAN:  Shall I tell you what rhymes with [the Octonauts submarine] GUP-A?  Buffet.

For the first time Dylan read a book by himself: Bad Cat, Ned!

AMY [Dylan's teacher]:  You look nice today, Dylan.

KITTY [rolling her eyes]:  Oh, he always wears that.

Dylan and Kitty have changed plans.  They now plan to live in a windmill in France.

DYLAN:  We're going to turn the sand pit into a paddling pool.  We're going to take all of the sand out of the sand pit and put it into the paddling pool, and we're going to take all of the water out of the paddling pool and put it into the sand pit.

Dylan has grown into a conscientious young man.

Isaac is red in tooth and claw.

Dylan often speaks to Daddy from inside locked toilet stalls.  'Daddy, I think this toilet paper dispenser was designed to save tubes and paper.  Shall I tell you how?  The roll comes out in cut pieces from the centre, with no tube'.

Isaac can say 'Dylan' (Din) and 'pigeon' (pin).

Dylan plans to have children with Kitty in America.  'Nana and Papa will look after our children on weekends', he said today.

Dylan gave his balance bike to Isaac and learned, on his second try, to ride his new peddle bike without assistance, even from a dead stop.

He also invented sugar-free green grape-flavoured moon-shaped ice cream.

For the first time, Isaac has called a non-duck bird by its real name:  chicken ('kee').  All other birds remain 'guck'.

DYLAN:  When I say 'Daddy', you have to say 'Yes, Dylan' straightaway.

New words from Isaac:  'boat', 'coat', 'gate', 'blow', 'pee', 'gnome'.

New words from Isaac:  'pool', 'catch'.

Isaac is counting!  (Or, at least, he's reciting the names of numbers in order, up to ten.)  We're surprised and not sure how he learned this.  (Daddy is really happy and proud.)
