Do you want to be in a routine? If she's feeding every 2 hours then that is a routine
I found ds was more in a routine at around 4-5 months, but that was more because I got on top of his napping, and feeds fell in around that - but still about 2.5 hourly in the day.
As for sleep, ds was actually doing at 8 hour stretch at that age, 7pm-3am. Unfortunately at 18 weeks he started waking every 45 minutes though, and didn't do an 8 hour stretch regularly til 9 months-ish. He only sometimes sleeps 8 straight hours now at almost 14 months (he is in bed 7.30pm-6.30am, he just wakes once or twice most nights!).
