Forget nursing to sleep, my baby has to sleep to nurse!

My 6 month old has always been a fussy nurser even though she’s great at it when she decides she wants to be. My problem is she MUST be almost dead asleep to eat or she is super fussy and will refuse to eat. Same with a bottle but I take it less personally. 😂

Any advice??? Do they grow out of this? It’s driving me bonkers and makes it so hard to ever leave the house. 😔
