What time should i wake my 3 and a half year old up?

[Gillyweed001]

Ds has for the past couple of days woken at 9am, and then gone straight back to sleep until 11am. He currently goes yo sleep at 9pm, wakes at 2 and 5:30am. Should I wake him earlier, say 8am?

Sorry! Title should say 3 and a half month old!

Hi I have a 3 mth old DD who was sleeping till 10am but wasn't going to sleep til 930pm each eve. I have 4 and 2 yr old ds's who go to sleep at 7pm and in order to get our evenings back I needed to get my DD to go to sleep at a similar time. 10 days ago I gradually started putting her to bed earlier And earlier, she now goes down at 8pm, wakes at midnight and 4am and is ready to star the day at 8am. I only did this as it fits in with us as a family. Dd was also so overtired which I mistook as colic. She happily goes off to sleep now. I guess if your ds is happy going to bed later and waking later suits you as a family then why break it.
