Chicago?
That’s not necessarily aging. Straws make everyone swallow more air, gives you more stomach gas too.
Aren’t the metal ones hard on your mouth? There are reports of people cutting the roof of their mouth where the straw poked them. I can’t imagine if a child tripped while drinking out of one.
We clean our straws with a baby bottle brush. I don’t sterilize my dishes, uneven had a reason to sterilize straws.
Haven’t been to WDW since they started this but on
DCL I had no issues with the straws. I had one in my cocktail for probably an hour during dinner and it never got mushy or fell apart.
Isn’t it like 90 in Chicago now? We’re in Springfield and it was 91 here.

My mom texted saying it was really hot at home too.
