I gave my son a milk bottle during the night when he was that age. You shouldn't send her to bed with it, because the milk (or water) can go into the ears and cause ear infections, but you can hold her and give her a milk bottle before putting her down.
When my son was that age and he woke up during the night, I would hold him and give him another milk bottle then too. Is your baby eatting solids yet? When I noticed my son was waking up frequently hungry at night, I would feed him a small bowl of oatmeal (Gerber oatmeal cereal) an hour or so before I was ready to put him down.
My son is 2 and I still give him milk (in a cup now) before I put him to bed. The doctors will tell you a lot of things, a lot of the time they are right, but sometimes their suggestions aren't right for your child. (An example, my doctors told me not to let my son take 2 hr naps, only 45 min to an hour. I know my son requires a lot of sleep, and if I wake him up there will be hell to pay all day!!) You know your child and what she needs.
