Ooh I love this question Andrea!
Here are some of the ones that I notice myself making:
“My brain is trying to pay attention to 2 things at once”
“My body feels not quite right” (really useful for kiddos with alexithymia or other issues where they can’t quite name the feeling/sensation)
“My chest feels tight, I think it wants to stretch”
“It’s like something heavy is pressing down on me”
“You’re right there next to me but it feels like you’re far away”
“I can’t feel you there” (I often use this one in 1:1s with hypoaroused parents to bring awareness to that sensation that the child may be feeling)
“It feels good to sit next to you”
