Sleep schedules.....?

please someone, i need a thourough schedule for my 3 month old daughter. she will sleep for 6-7 hours,eat, then sleep again for a while, but when should i put her to bed and get her up for the day.... it doesnt have to coincide with my sleep schedule because i dont have one, i go to bed between 10pm and 2am, and usually just wake up when kayla does....but i dont want her to get into my habit....thanks!
