We bath at 5.30pm and then story, bottle etc so Grace is in bed about 6 - 6.30pm - she seems to need a lot of sleep and I've also found the more she has during the day, the better she sleeps at night (although I try not to let her sleep after 4 as he bedtime is so early)
I'm sure she'd sleep from 5pm if I gave her the chance - she's a lazy little monkey xx
