I didn't give my DD a bottle at all yesterday. She's 14.5 months. Ped. said it's time to quit. I offered the sippy with water and milk all day and with meals. She gladly took the water but was reluctant to drink milk from it. So her intake of milk was very low for the day (3-4 oz), however she had 2 string cheeses and ate her other regular foods well. She's on day 2 now, just finished breakfast, sipped water but doesn't want anything to do with milk from the bottle. I know if I cave and give her the bottle, she'll guzzle it. I don't want to cave but I hope she gets the hint and starts drinking her milk.
