Your lo sounds like she is doing FANTASTIC!!!! She could be going through a growth spurt which is causing the wakings, however, if she is NOT crying....I would probably leave her to fall back to sleep.
If she is crying, chances are she is hungry and should be fed. Growth spurts last just a few days.
If you'd like, post your current routine and it might help us better determine if it is a growth spurt or habitual waking!
