Feeling irked by daycare teacher labelling toddler friendship

My LO is 20 months old and is in a lovely daycare that she’s been at since she was 13 months.

Due to her teachers going on maternity and paternity leave, they are bringing in new teachers. And one such new teacher, she starts talking about a boy that he keeps saying my daughter’s name constantly and goes like - I think (my daughter’s name) has a new boyfriend. And she said his name. I know the kid, he was there with her in infant room.

The first day she said I just smiled and my husband does the whole thing of putting her jacket on so he didn’t focus on what she said. And the head teacher wasn’t there in the room.

The car ride back home I felt weird as to why she would say that.

The next day we go pick her up and she repeats the same thing. She tried to pick up some reaction from us but my husband keeps a straight face and me too, since we are more focused on getting our daughter ready to step out. But since the head teacher was there, I think that was the last time I heard her saying and that was last week.

Now I keep thinking why this labelling? Because I had another mom with daughter the same age say this who sends her daughter to a different daycare.

I was almost ready to argue the next time this came up but she dropped it by herself which I feel good about

I would like to mention this post is more of a vent or rant or even a topic to start a discussion. I’m not planning to complain about the teacher since other than that I have not had any such weird things happening at her daycare. Any thoughts on this? Is it just me who feels weird about this?
