Hi
My son turned two this month he has quite a few single words I'd imagine over 70 don't have an exact number as he's come out with words recently that I didn't know he knew.
But no 2 word phrases that is until a couple of weeks ago but im not sure whether they would count as they're not a verb noun combination.
A couple of weeks ago my son came up to me with the Bubble wand and said "daddy bubbles" giving me the bubble wand wanting to make bubbles. But is this what is regarded as a 2 word phrase in the literal sense it is but from a functional language point of view.
Also walking through nottinghill and a train went past he looked at the train going by and said "bye bye train."
Other phrases used are "thank you" and "there you go" both used in the right context. But I believe these would have been learnt parrot fashion as his mother always says there you go when she gives him something,
