Does he nap?
He sounds potentially over-tired.
Also kids at this age have night-mares.
And they also developmentally, start to have night time 'fears.'
When my son is over-tired, he has a lot of dreams/nightmares. For example. And he is a noisy sleeper. He even talks in his sleep.
or about things that irked him earlier in the day.
Or, is any molars coming in? ie: teething. Molars hurt more.
Also perhaps, he has no routine yet. Being you all moved.
And he began potty training.
So many things, affecting him.
But, I would make sure he naps. If he is not.
At this age they still need naps.
Being over-tired, actually makes it harder for kids/babies to sleep and sleep well. And they wake more.
