That's hard 
I thought S was bad enough (she's almost 10 months), also a BFed baby. She was taking a bottle fine on child minder days when I'm at work, but this week has gone on bottle and beaker strike, so is pretty much dehydrating herself all day until I get home around 6pm, having left the house at 7am. So on wirk nights, she then wants to feed all evening and most of the night, and is also newly refusing to feed laying down, so I am beyond knackered and effing fed up with it.
I can't imagine how you most feel with 9 months of it though. One week has been bad enough for me. At least she doesn't mind being on her own, so I'm not holding her all the time.
I don't know the answer for you, but I hope things change for you soon and you get some 'you time' back again.
