Yes, the times have changed a bit. Don't laugh too loudly, though. I have seen baby bottles out there shaped like 7up soda bottles. Half the "juice" they sell for kids is high-fructose corn syrup with water and coloring added... soda pop without the bubbles.
But gosh... can you imagine giving a baby a bottle of Coke? I dunno Our kids don't drink pop, except the very occasional Sierra Mist or, when we go to the old general store downtown, they'll get a glass bottle of grape Nehi. I can't imagine what the caffeine booster would do... to me, not to them!
