Hi D.,
Everyone does the transition different. I had a thing with warm liquids in the sippy cup. Just my weirdness, so my rule of thumb was milk, which I didn't warm, would leave out for a few mins. maybe, would be in a cup. Bedtime, if I gave a warm milk before bed, would still be in the bottle. Juice and water, I never warmed, went in the sippy. Everyone has their own rule of thumb, and this was mine. I hope it amuses you!!!!
