If talking helps with that, then okay. I'm pretty wordy online, but in meat space I actually don't process very quickly in words, and can be easily overwhelmed by too much talking. But ironically I learned to defend myself from talking by talking - and when Ray was little, keeping up a kind of stream-of-consciousness ramble helped him feel connected. So I got good at blathering... and then Mo came along and started saying "shush" to me when she was 2. Oh my! Suddenly all my handy strategies weren't useful any more. But since I'm secretly not all that verbal, it was also kind of a relief to be able to hush up and tune into my other senses.
I think a lot of the time people think of non-verbal communication just in terms of body language, and that's certainly a part of it, but another part is observing the situation on a broader level, tuning in to the environment and what's going on Around another person that may be effecting them, as well as how they're moving through space, where they're oriented and how intently. It's also important to step back in terms of time - think back and think ahead so that the moment makes sense in that context. Notice patterns. Sometimes people talk about unschooling in terms of freedom and flow, but the patterns in the flow are super important - what are your kid's touchstones as they move through the day? When does their energy rise and fall? When are they more talky versus more physical? And with more than one kid, how do they reflect off each other in different times, different moods, different circumstances?
That can be kind of frustrating when you're still new to it because you want to know what to do When Something Happens - and here come the unschoolers going on about the past and planning ahead and not saying much about That Moment when it's all going down Learning a new kind of situational and temporal awareness, though, is a big part of how those moments become less frequent and more manageable.
