ainsley, when you are feeding on 1 side, use your other arm/ hand to press onto your other breast to stop the flow and let down reflex, especially useful when you have such forceful letdown. Also since you are dripping in the shower, you can do some hand massage and ease the flow there and then. Before feeding baby, you can try to hand massage to stimulate your let down so that some milk can flow out before your baby drinks so she doesn't choke.
