My daughter is just 1 year old and she sleeps at 10pm, sometimes 11pm. She wakes up at 730-8am. Our pedia says it's okay. We tried making her sleep around 7pm but she always wakes up whenever we arrive from work (around 8pm), and will fall asleep past midnight.
If you really want your baby to sleep early, let her play in the afternoon so that she'll get tired and will be sleepy after dinner.
