Potty training help!!!!!!!

Ok my daughter is 2 1/2 and she’s still in diapers she knows when she has to pee and poop . To pee few times she’s gonna pee on the toilet but poop she won’t but she tells me right after she poops that she did and asked to be changed .. how did y’all do it? And what age or about what age did your girls get out of diapers? Also she has a bottle to go to sleep at night one bottle only but all day she drink out the straw or soda can or cup with no lid and if she naps she just falls asleep . I’m need advice on if this is ok for her age or what.... my sister are constantly!!!!!!!!! Putting me down as a mother about this they always say omg! She’s gonna be 40 still in diapers and drinking a baby bottle .. I don’t feel it’s bad my dr even said don’t rush it every kid lets go of the bottle an passy at different-times / ages
