Yes, my youngest was like that and it's hard. Have you tried putting her in a swing to sleep? Mine would sometimes sleep in a swing that went side to side instead of front to back. Also, you could try a baby carrier, like a Moby wrap, so you could wear her down to sleep. The other thing that used to work for me was to put him in the car, drive until he fell asleep, and then transfer him to the crib, or leave him in the infant seat for a while.
Another thought...could she have reflux? That could be why she has a hard time sleeping/gets cranky after she eats, and you could ask your ped about that.
It's hard when they're so little, but hang in there!
