We transitioned from the bottle to the straw sippy cup quite easily. I also put Ovaltine in his milk which I think helped a lot. I also had a sippy cup of water/juice sitting out for him. Each day I took away one bottle....nap, nap, nighttime. It was a rough couple of days, but eventually he took to the sippy cup without fussing. He was off bottles completely in about 4 days.
