Anyone have their baby skip sippy cups and go straight to drinking out of a 360 cup? My son was exclusively breastfed until about a month ago. We got the handles for his tommee tippee bottles to give at dinner, but I'm wondering if we can give him a 360 cup next instead of moving on to the traditional sippy cups from the bottle. He's 6 and a half months old and is not picky about bottles or breastfeeding at all if that makes a difference. Thoughts/opinions?
