Uncomfortable scenario

I have had a hard time with how my coteacher interacts with our toddlers. We have had a child having health concerns lately but has been totally fine this week. But now this particular child is at a point of an attachment with this teacher that leaves the classroom she bursts into uncosoleable tears and almost panic striken.
This child has NEVER been this sensitive or needing a particular teacher at all times. She also always played independently. 2 times today I had said "Hey name, let's come play". Because she literally would never leave the teachers side. The teacher encourages this attachment to continue for example let her sit in her lap or carrying , no ability problems, her around.

Like mentioned before this particular child never behaved like this in the past and I really don't want her to feel that she can't even play without being on top with this particular teacher . The teacher even quipped and said : See (name) I care for your well-being

Almost as if she did not think that I did. I just don't adhere to being 1:1 with a child for the entire day, unless extenuating circumstances.

How /should I adress this? I was thinking of giving it another few days so that the child is comfortable again with our routines and separation. And to emphasize she has been perfectly healthy all week.

Thank you for any help and your time reading.
