Is your baby encountering the same?

I don't think it's claustrophobia, but more likely just disliking to lay down coz they're at an age when they can stand. Mine yells his head off when I put him to lying down position coz he doesn't like lying down haha. Offer the kid a toy or something to distract them with,like a clean diaper or whatever u have lying around

Try offering her a teether cracker. It works for my LO who recently hate laying down on her back for a diaper change.

i doubt claustrophobia... hope this phase passes quickly
