Is it true that she will "find her own routine"????
Yes

We never worried too much about bed time when they were that age.. Just when they went down for an evening nap they went into their bedroom but most other naps were in the lounge..

for example.. If bub went down for a sleep around 5ish then we would pop them in their cot.. any other day time nap was out in the lounge with us. We didn't do it for any other reason except we liked them close..

Around 10-11 months all 4 of my kids have worked their own way into a 7pm bedtime and we still have that now..

When bub is awake at 11 do you have all the lights on ect? When my bubs were awake at that time I would still watch tv or play on the comp but I would turn out the lights so they knew it was bedtime.. Occasionally I would go lay down with them when I was really tired just so they would go to sleep..

I am sure soon enough your little one will be sleeping at that hour.. Does she sleep through from 11 and till what time?
