LO 2 (3.5) loves her two regular teachers but she refuses to speak to a floater teacher that she sees a couple times a week. This teacher says LO only communicates with her non verbally or ignores her.
LO has mentioned a few times that this teacher is always so "cranky" and she isn't "nice" but won't elaborate.

LO was crying hysterically when I picked her up yesterday. The floater teacher told me that she tried to "force" LO to answer a question (about her C share object) repeatedly for a few minutes because she is tired of seeing her mute. The teacher apologized for the situation but said she is a little frustrated because LO talks to her peers and other teachers. I suggested that we set something up with the director (who is on vacation) for next week.

Ugh, any suggestions? I don't want LO to ignore her but I also don't want to force it.
