DD is 13 weeks currently goes to bed at 10pm and sleeps 7-8h which is great. I keep reading and hearing folk say that this is too late and bed should be around 7-8pm. I tried that but she didn't have the nice long sleep and instead woke at 2am and 5am. Am I being selfish to keep her up til 10pm? She does sleep in the evenings but they are naps down in the lounge with us.
