When DS was around that age he'd wake 2-3 times a night.
He's now 15 months and still wakes that often.
We did go through a stage of him waking almost every hour, so I feel your pain!
Are you b'feeding? Perhaps she may be going through a bit of a growth spurt?
Could pain be the reason she's waking? Perhaps she has some wind?
I hope someone will come in and give you some further advice!
Hugs to you
