does that even make sense?

I offer LO a sippy with every snack/meal, and wash it after - she gets a new cup, new juice/water next time.

When did you start just popping it into the fridge if they didn't finish it?

I know with bottles of bm/formula, you aren't supposed to reuse after a small window, same with double-dipped baby food. When does this end?

ETA - She is 7.5 months!
