As others have stated, each child is different. You're best bet is to take your cues from your little ones. My oldest had a bottle until he was 3 yrs old (night time only by then). My second gave it up herself completely by her 2nd birthday. Our little one came to us at 10 mos and it took a bit of coaxing to get her to take the bottle at all. Now at 14 mos. she's doing fine and shows zero interest in the cup. I put one on her tray and she plays with it but won't even bring it to her lips. Her OT thinks that the new sippy cups with the straw (they are little with handles; versus the tall ones for older children) are better. Our daughter is speech delayed and her therapist feels that the straw works the facial muscles more than the sippy with the spout. I mention this as an FYI in case others are experiencing the same delays. In any event, as my Grandmother would say "Don't worry, I never knew a child who went to Kindergarten with a bottle".
