Is your daughter drinking FM or EBM or direct latching? How many solids per day?
For my son, he's on direct latch and when he was 9 months old, still woke up once or even twice for milk. His bedtime also the same 8-8.30pm, woke up around 1+am, then sometimes 4+am again. I gave him 2 solids a day then (lunch and dinner).
By 10 months, I gave him 3 solids, breakfast, lunch dinner. It was only towards 11 month old, he began to sleep through i.e. 8-8.30pm to 6.30-7am. But when he was 12 month old, he fell sick for one week and for two weeks, he once again woke up a few times to drink milk. Probably coz he didn't eat much for one plus week thus making up for the loss nutrients.
Recently (13 months old), he began to sleep through again. I gave him breakfast, lunch, dinner. In between, some snacks like biscuits, bread, fruit, yogurt. Probably he got enough food during the day, so can last through now.
I think when she's ready, she will sleep through.
