@Alyssa why ?
I found that it was less heavy to hold while feeding and I didn’t haven’t to worry about any breakage.
We like the glass to see the measurements less than 2oz
I have both and I noticed that the measurements are different
I prefer glass in general because it's recyclable and you don't have to replace them every few months like you do with plastic.
Definitely plastic.. there’s always a risk of dropping it and it smashing then you end up stepping on glass you’ve missed
We prefer the plastic
