His speech currently is minimal. After much intensive work with him since his regression, he now says "ball" relatively clearly. He says "plass" for splash (originally from Peppa pig
). If he wants me to wear his pirate eyepatch or to watch Jake and the Neverland Pirates, he can say "Arrr".
If I put his Mickey Mouse t-shirt on and ask him "who's that?" He will reply "Mmmm".
He hasn't said Mum or Dad for four months now though, since his regression. 
He IS now following simple instructions like sit down, show me splash, brush mummy's hair, and understanding some of what I say - if I hold his socks and ask him "Where do socks go?" He will hold his foot up.
So his receptive language is slowly improving.
He still isn't pointing, and he's 22 months now. He never has, despite me modelling it by pointing at birds, cars, tractors, trees, anything, he still won't point himself.
He also has made up a couple of signs - he shakes his right hand up and down when he wants milk, as it mimics the action I do when I am shaking his bottle to mix the Nutramigen powder into the water. He also makes circles from the thumb and forefinger of both hands, meets the points, and puts them on his forehead to denote glasses whenever he sees someone wearing glasses.
A lot of his communication is non verbal still though - when he wants me to put his car mat out for him, he will drag it over to me, literally PUT the car mat in my hand, and stand waiting expectantly for me to do it.
If he wants more juice, he will stand in front of me with his beaker in his mouth. Then he puts the beaker in my hand. No amount of attempts to get him to say or sign juice are getting me anywhere.
Last night he was pushing my head to DD's belly because he wanted me to blow raspberries on her.
If he wants me to pretend to 'get' him with his foam sword, he will put it in my hand and stand expectantly. If I don't start waving it around, he grabs my hand and MAKES me move it around.
So his expressive language is still not really getting anywhere.
I would say that his receptive language is at about 15mo level, and his expressive language at about an 11mo level.
We shall see what SALT say on Thursday...
