Hey y'all

So my soon to be two year old just started preschool and when ever he sees the floor supervisor he gets so excited and loves it and never notices me when I leave nor does he cry but whenever I drop him off to his actual class room teacher he always cries . Granted it's only been two week

I'm wondering if anyone experienced this and if it eventually goes away .

I'm just worried that it might be an early sign and that he just doesn't like his teacher .

His first two days of class he was with the floor supervisor because his teacher was absent so I'm wondering if he only takes to her because he first met her .

I also noticed that the floor supervisor is so much happier when she she's my son and gives him such an elaborate welcoming vs his actually teacher isn't as exaggerated .

Am I over thinking this or should I be worried , does anyone have a child who eventually warmed up to the teacher when they didn't at first ?

Thanks in advanced
