My very alert, smiley, lovely DS babbles LOADS and shouts a lot. He shouts to get attention, I think, in the absence of words, but he does shout really loudly. And at night, he groans and shouts in his sleep - so loudly we wake up continuously but he doesn't (much, occasionally).
It's quite wearying. Please can someone tell me it will pass? and why he's doing it in his sleep?
