I’m looking for an easy-to-clean straw water bottle for my 1.5 yo.. any recommendations? Prefer stainless steel but definitely open to plastic too.

We used the very popular thermos funtainer for 4 kids, 8 years… and this whole time we have hated cleaning the silicone top. It gets moldy and gross and I hate popping it off every time. I can’t believe we haven’t switched straw water bottles for this long but we are finally doing it!!
