18 months old

Last Tuesday he turned 18 months. I haven't done any overview of what he can do in a while but this feels like a milestone, so here it goes:

He has 4 teeth so far.
The biggest surprise of the week: He can throw all the shapes in the shape sorter - it came totally out of the blue because he didn't play with it for a while and suddenly he was doing it.
He can go up and down the stairs without holding, especially when he has full hands or is chasing pigeons (in the city centre)
He can do those one piece wooden puzzles and also two-piece puzzles.
He loves reading books, signing and making sounds.
He loves to play with his cars and train.
He loves loves loves the dog, he is his most favourite toy, he would like to fall asleep cuddled with him but Charlie is a jerk who doesn't like it.
He loves to stamp and draw.
He loves to ride his motorbike and run outside and jump from curbs.
He loves to rock on his rocking horse.
He loves to play with his bead mazes.
He loves to build towers.
He likes to throw coins to the pig (coin box).
He enjoys learning different parts of bodies (he now knows that a duck has a beak, dogs/cat have muzzle, etc.), he also is interested in part of cars.
He also likes throwing balls, especially to Charlie.
He can wash his head.
He can open his zips and take of his jacket with a little bit of a help. He can't do much of self-care because I don't pay much attention to it.
He still doesn't sleep through the night, he still nurses at night and during the day. He can't fall asleep on his own.
