Because I don’t want to eat before I’ve gotten rid of my morning breath.

Yup, this makes sense.

I totally get all of that. Wouldn’t all of that hold true if you were having breakfast on a table/kitchen island too though? I’m specifically confused about what makes having it in bed special.

I suppose you don’t HAVE to. But I find it unhygienic to eat before brushing my teeth as soon as I wake up. Might just be my personal issue. 🤷‍♂️
