What are you moms using to give milk?

This is my third. With my first and did the milk transition then bottle transition - it was just fine but it was a whole thing to wean bottles. With my next two, I just went straight to cups.

I actually switched my first to sippy cups for one feed per day and that went well

My son is 9 months. We do almost exclusively sippy or straw cups from 6-7 months, with open cups for meals. The only time we use an actual bottle any more is if we get behind on dishes and everything else is dirty.
