I used to teach PreK and it was always VERY important to me to know about these things. And let me tell you, I loved those kids with every bit of my heart. (Honestly, it helped keep me in my home.) I had two last year with families separating, and when they were having an off day, sometimes they just got some extra time on my lap, things like that. And I knew when to say to a parent..hey Child seems angry today. Things like that. Let these teachers help you. They've heard it before, so don't be embarrassed.
Also, Tom, kids say things. You don't know what odd comment either of them could have dropped.
Funny story...I had a kid last year tell me..."My daddy wears dresses." And I say...oookaaay. I think you're being silly.
