Sleep Schedules for a Baby?

Sharon
We all know that neqborns sleep a lot and then move into taking scheduled naps. My daughter is 2 months old and is on a schedule but not one that works with my 5 year old. She sleeps a lot during the day and is awake most of the night which leaves little time for me to sleep before my 5 year old wakes up at 8am. Is 2 months too young to try changing her sleep schedule? Should I try keeping her up more during the day so she'll sleep at night? Or should I just let he sleep during the day and stay up all night with her until she changes her own schedule?
