I think if it works for you - it's fine. She'll soon let you know if she's not happy with it

Once Moo got into a routine, he's always gone to bed early. It used to be 6pm but I've managed to stretch him out to at least 6:30pm for quite some time now. It's not set in stone though we're pretty flexible and the last few nights he didn't go down until after 9pm. He'd napped late and just wasn't tired.
