I bought my daughter a cup at 4mths although she couldnt realy drink from it i just kept giving it to her not to substitute her milk bottle just instead of putting water or juice in a bottle. (i hate it when i see juice in bottles) she is now 7mths and knows how to use her cup it is still used only for juice and water. you dont really need to worry about taking him off the bottle aslong as it is used for milk only and never put him to bed with it and when he's older dont let him play or walk around with it. I bought a tommee tipee cup. it has removable handle and grips on the handles also the teat of the cup is still a similar feel to a bottle teat I paid around $7-$8 at Kmart for it.

My little man is 2, and drinks from his cup most of the time, but he still loves a bottle of milk before a nap/bed. it really is up to the child. as the other parents have said, bubs will let you know.

i agree with the others, just let bubs play with a cup and see what happens. i can reccomend the heinz sipper cups, you can get them with removable handles, and are designed with grips for little hands. they are a bit more expensive, but you pay for quality, and last quite a while!.

hope this helps
