11 month old goes to sleep about 7pm and sleeps until about 5am (I know this is great - we've had to work hard to drop bottles/self sooth over many months to get to this point).
Any suggestions for how to get him to get sleep just a bit longer to after 6am? I just can't stretch another hour. He wakes his older sister then too.
He has two naps during the day, and bottles first thing and before bed. Eats well. No other issues. We have blackout curtains.
