a child's sleep patterns are set by 3-4 yrs. its too early to expect anything at all. what you can do is try and put the child into a schedule. like put baby sleep by 8pm. switch on some dim light, and feed the baby. do the same schedule everyday.

At such an age baby doesn't know day or night. Gradually once she sees more activity in the day and not in night she ll sleep more. Just ensure baby is fed well and burped.
